Если вы похожи на меня, вы сначала попробуйте все в своем коде и исправить ошибки, как они приходят. Одна частая ошибка в Python – IndentationError: неожиданный отступ Отказ Итак, что означает это сообщение об ошибке?

Ошибка . IndentationError: неожиданный отступ Возникает, если вы используете непоследовательную отступ вкладок или пробелы для блоков кода с отступом, таких как Если блок и для петля. Например, Python бросит ошибку вдавливания, если вы используете для петля с три персонажа пробелов Отступ для первой строки и Один символ вкладок отступ второй строки корпуса петли. Чтобы устранить ошибку, используйте одинаковое количество пустых пробелов для всех блоков кода с отступом.

Давайте посмотрим на пример, где возникает эта ошибка:

for i in range(10):
  print(i)
   print('--')

Первая строка в корпусе петли использует два пробела в качестве уровня вдавливания. Вторая строка в корпусе петлей использует три персонажа пробелов в качестве уровня отступа. Таким образом, блоки вдавливания различны для разных линий того же блока. Однако Python ожидает, что все линии с отступом имеют структурно те же отступ.

Чтобы исправить ошибку, просто используйте одинаковое количество пробелов для каждой строки кода:

for i in range(10):
    print(i)
    print('--')

Общая рекомендация состоит в том, чтобы использовать четыре единственных пробелных персонажей '' для каждого Отступ уровень. Если у вас вложенные уровни вдавливания, это означает, что второй уровень вдавливания имеет одновение пробелы:

for i in range(10):
    for j in range(10):
        print(i, j)

Смесительные вкладки и пробелы частоты часто вызывают ошибку

Общая проблема также в том, что вдавливание, по-видимому, является последовательным – пока это не так. Следующий код имеет один символ вкладки в первой строке и четырех пустых пробеле во второй строке блока кода с отступом. Они выглядят одинаково, но Python все еще бросает ошибку вдавливания.

На первый взгляд углубление выглядит одинаково. Однако, если вы пройдете пробелы перед Печать (I) , вы видите, что он состоит только из одного табличного характера, в то время как пробелы перед Распечатать (j) Заявление состоит из ряда пустых мест '' Отказ

Попробуйте сами: Прежде чем я скажу вам, что делать с этим, попробуйте исправить код себя в нашей интерактивной оболочке Python:

Как исправить ошибку отступа на все времена?

Источник ошибки часто является неправильным использованием вкладок и пробеловных символов. Во многих редакторах кода вы можете установить символ вкладки на фиксированное количество символов пробела. Таким образом, вы, по сути никогда не используете сам табличный символ. Например, если у вас есть Sublime Text Editor, следующее быстрое руководство гарантирует, что вы никогда не будете работать в этой ошибке:

  • Установить Возвышенный текст Использовать вкладки для отступа: Вид -> Отступ -> Преобразовать вдавшиеся вкладки
  • Снимите флажок Опция Отступ с использованием пробелов в том же подменю выше.

The IndentationError: Unexpected indent error indicates that you have added an excess indent in the line that the python interpreter unexpected to have. An unexpected indent in the Python code causes this indentation error. To overcome the Indentation error, ensure that the code is consistently indented and that there are no unexpected indentations in the code. This would fix the IndentationError: Unexpected indent error.

The IndentationError: Unexpected indent error occurs when you use too many indent at the beginning of the line. Make sure your code is indented consistently and that there are no unexpected indent in the code to resolve Indentation error. Python doesn’t have curly braces or keyword delimiter to differentiate the code blocks. In python, the compound statement and functions requires the indent to be distinguished from other lines. The unexpected indent in python causes IndentationError: Unexpected indent error.

The indent is known as the distance or number of empty spaces between the start of the line and the left margin of the line. Indents are not considered in the most recent programming languages such as java, c++, dot net, etc. Python uses the indent to distinguish compound statements and user defined functions from other lines.

Exception

The error message IndentationError: Unexpected indent indicates that there is an excess indent in the line that the python interpreter unexpected to have. The indentation error will be thrown as below.

 File "/Users/python/Desktop/test.py", line 2
    print "end of program";
    ^
IndentationError: unexpected indent

Root Cause

The root cause of the error message “IndentationError: Unexpected indent” is that you have added an excess indent in the line that the python interpreter unexpected to have. In order to resolve this error message, the unexpected indent in the code, such as compound statement, user defined functions, etc. must be removed.

Solution 1

The unexpected indent in the code must be removed. Walk through the code to trace the indent. If any unwanted indent is found, remove it. The lines inside blocks such as compound statements and user defined functions will normally have excess indents, spaces, tabs. This error “IndentationError: unexpected indent” is resolved if the excess indents, tabs, and spaces are removed from the code.

Program

print "a is greater";
	print "end of program";

Output

 File "/Users/python/Desktop/test.py", line 2
    print "end of program";
    ^
IndentationError: unexpected indent

Solution

print "a is greater";
print "end of program";

Output

a is greater
end of program
[Finished in 0.0s]

Solution 2

In the sublime Text Editor, open the python program. Select the full program by clicking on Cntr + A. The entire python code and the white spaces will be selected together. The tab key is displayed as continuous lines, and the spaces are displayed as dots in the program. Stick to any format you wish to use, either on the tab or in space. Change the rest to make uniform format. This will solve the error.

Program

a=10;
b=20;
if a > b:
	print "Hello World";      ----> Indent with tab
        print "end of program";    ----> Indent with spaces

Solution

a=10;
b=20;
if a > b:
	print "Hello World";      ----> Indent with tab
	print "end of program";    ----> Indent with tab

Solution 3

In most cases, this error would be triggered by a mixed use of spaces and tabs. Check the space for the program indentation and the tabs. Follow any kind of indentation. The most recent python IDEs support converting the tab to space and space to tabs. Stick to whatever format you want to use. This is going to solve the error.

Check the option in your python IDE to convert the tab to space and convert the tab to space or the tab to space to correct the error.

Solution 4

In the python program, check the indentation of compound statements and user defined functions. Following the indentation is a tedious job in the source code. Python provides a solution for the indentation error line to identify. To find out the problem run the python command below. The Python command shows the actual issue.

Command

python -m tabnanny test.py

Example

$ python -m tabnanny test.py 
'test.py': Indentation Error: unindent does not match any outer indentation level (<tokenize>, line 3)
$

Solution 5

There is an another way to identify the indentation error. Open the command prompt in Windows OS or terminal command line window on Linux or Mac, and start the python. The help command shows the error of the python program.

Command

$python
>>>help("test.py")

Example

$ python
Python 2.7.16 (default, Dec  3 2019, 07:02:07) 
[GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.37.14)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> help("test.py")
problem in test - <type 'exceptions.IndentationError'>: unindent does not match any outer indentation level (test.py, line 3)

>>> 
Use exit() or Ctrl-D (i.e. EOF) to exit
>>> ^D

    1. Python and PEP 8 Guidelines 
  2. Solving IndentationError: expected an indented block
  3. Example 1 – Indenting inside a function
  4. Example 2 – Indentation inside for, while loops and if statement
  5. Conclusion

Python language emphasizes indentation rather than using curly braces like other programming languages. So indentation matters in Python, as it gives the structure of your code blocks, and if you do not follow it while coding, you will get an indentationerror: unexpected indent.

What are the reasons for IndentationError: unexpected indent?

IndentationError: unexpected indent mainly occurs if you use inconsistent indentation while coding. There are set of guidelines you need to follow while programming in Python. Let’s look at few basic guidelines w.r.t indentation.

Python and PEP 8 Guidelines 

  1. Generally, in Python, you follow the four spaces rule according to PEP 8 standards. 
  2. Spaces are the preferred indentation method. Tabs should be used solely to remain consistent with code that is already indented with tabs.
  3. Do not mix tabs and spaces. Python disallows the mixing of indentation.
  4. Avoid trailing whitespaces anywhere because it’s usually invisible and it causes confusion.

Solving IndentationError: expected an indented block

Now that we know what indentation is and the guidelines to be followed, Let’s look at few indentation error examples and solutions.

Example 1 – Indenting inside a function

Lines inside a function should be indented one level more than the “def functionname”. 

# Bad indentation inside a function

def getMessage():
message= "Hello World"
print(message)
  
getMessage()

# Output
  File "c:ProjectsTryoutslistindexerror.py", line 2
    message= "Hello World"
    ^
IndentationError: expected an indented block

Correct way of indentation while creating a function.

# Proper indentation inside a function

def getMessage():
    message= "Hello World"
    print(message)
  
getMessage()

# Output
Hello World

Example 2 – Indentation inside for, while loops and if statement

Lines inside a for, if, and while statements should be indented more than the line, it begins the statement so that Python will know when you are inside the loop and when you exit the loop.

Suppose you look at the below example inside the if statement; the lines are not indented properly. The print statement is at the same level as the if statement, and hence the IndentationError.

# Bad indentation inside if statement
def getMessage():
    foo = 7
    if foo > 5:
    print ("Hello world")
  
getMessage()

# Output
  File "c:ProjectsTryoutslistindexerror.py", line 4
    print ("Hello world")
    ^
IndentationError: expected an indented block

To fix the issues inside the loops and statements, make sure you add four whitespaces and then write the lines of code. Also do not mix the white space and tabs these will always lead to an error.

# Proper indentation inside if statement
def getMessage():
    foo = 7
    if foo > 5:
        print ("Hello world")
  
getMessage()

# Output
Hello world

Conclusion

The best way to avoid these issues is to always use a consistent number of spaces when you indent a subblock and ideally use a good IDE that solves the problem for you.

IndentationErrors serve two purposes: they help make your code more readable and ensure the Python interpreter correctly understands your code. If you add in an additional space or tab where one is not needed, you’ll encounter an “IndentationError: unexpected indent” error.

In this guide, we discuss what this error means and why it is raised. We’ll walk through an example of this error so you can figure out how you can fix it in your program.

IndentationError: unexpected indent

An indent is a specific number of spaces or tabs denoting that a line of code is part of a particular code block. Consider the following program:

def hello_world():
	print("Hello, world!")

We have defined a single function: hello_world(). This function contains a print statement. To indicate to Python this line of code is part of our function, we have indented it.

You can indent code using spaces or tabs, depending on your preference. You should only indent code if that code should be part of another code block. This includes when you write code in:

  • An “if…else” statement
  • A “try…except” statement
  • A “for” loop
  • A “function” statement

Python code must be indented consistently if it appears in a special statement. Python enforces indentation strictly.

Some programming languages like JavaScript do not enforce indentation strictly because they use curly braces to denote blocks of code. Python does not have this feature, so the language depends heavily on indentation.

The cause of the “IndentationError: unexpected indent” error is indenting your code too far, or using too many tabs and spaces to indent a line of code.

The other indentation errors you may encounter are:

  • Unindent does not match any other indentation level
  • Expected an indented block

An Example Scenario

We’re going to build a program that loops through a list of purchases that a user has made and prints out all of those that are greater than $25.00 to the console.

To start, let’s define a list of purchases:

 purchases = [25.50, 29.90, 2.40, 57.60, 24.90, 1.55]

Next, we define a function to loop through our list of purchases and print the ones worth over $25 to the console:

def show_high_purchases(purchases):
	   for p in purchases:
		        if p > 25.00:
			            print("Purchase: ")
				                print(p)

The show_high_purchases() function accepts one argument: the list of purchases through which the function will search. The function iterates through this list and uses an if statement to check if each purchase is worth more than $25.00.

If a purchase is greater than $25.00, the statement Purchase: is printed to the console. Then, the price of that purchase is printed to the console. Otherwise, nothing happens.

Before we run our code, call our function and pass our list of purchases as a parameter:

show_high_purchases(purchases)

Let’s run our code and see what happens:

  File "main.py", line 7
	print(p)
	^
IndentationError: unexpected indent

Our code does not run successfully.

The Solution

As with any Python error, we should read the full error message to see what is going on. The problem appears to be on line 7, which is where we print the value of a purchase.

	if p > 25.00:
			print("Purchase: ")
				    print(p)

We have incidentally indented the second print() statement. This causes an error because our second print() statement is not part of another block of code. It is still part of our if statement.

To solve this error, we need to make sure that we consistently indent all our print() statements:

	if p > 25.00:
			print("Purchase: ")
			print(p)

Both print() statements should use the same level of indentation because they are part of the same if statement. We’ve made this revision above.

Let’s try to run our code:

Purchase:
25.5
Purchase:
29.9
Purchase:
57.6

Our code successfully prints out all the purchases worth more than $25.00 to the console.

Conclusion

“IndentationError: unexpected indent” is raised when you indent a line of code too many times. To solve this error, make sure all of your code uses consistent indentation and that there are no unnecessary indents.

Now you’re ready to fix this error like a Python expert!

If you are new to coding or an experienced coder, you might have come across indentation error in python. It looks silly but it can pause the entire process and take good amount of time to fix it. I can help you saving some of your precious time. So, lets dive little deeper into it and understand what is indentation and how to fix it

Python is a procedural language. An indentation in Python is used to segregate a singular code into identifiable groups of functionally similar statements. The indentation error can occur when the spaces or tabs are not placed properly. There will not be an issue if the interpreter does not find any issues with the spaces or tabs. If there is an error due to indentation, it will come in between the execution and can be a show stopper.

Python follows the PEP8 whitespace ethics while arranging its code and therefore it is suggested that there should be 4 whitespaces between every iteration and any alternative that doesn’t have this will return an error.

Below are some of the common causes of an indentation error in Python:

  • While coding you are using both the tab as well as space. While in theory both of them serve the same purpose, if used alternatively in a code, the interpreter gets confused between which alteration to use and thus returns an error.

  • While programming you have placed an indentation in the wrong place. Since python follows strict guidelines when it comes to arranging the code, if you placed any indentation in the wrong place, the indentation error is mostly inevitable.

  • Sometimes in the midst of finishing a long program, we tend to miss out on indenting the compound statements such as for, while and if and this in most cases will lead to an indentation error.

  • Last but not least, if you forget to use user defined classes, then an indentation error will most likely pop up.

Errors due to indentation in Python:

Python determines when code blocks begin and stop by looking at the space at the beginning of the line. You may encounter the following Indentation errors:
1. Unexpected indent — This line of code has more spaces at the beginning than the one before it, but the one before it does not begin a sub block. In a block, all lines of code must begin with the same string of whitespace.
2. Unindent does not correspond to any of the outer indentation levels — This line of code contains less spaces at the beginning than the previous one, but it also does not match any other block.
3. An indented block was expected — This line of code begins with the same number of spaces as the previous one, yet the previous line was supposed to begin a block (e.g., if/while/for statement, function definition).

Few tips to solve an indentation error in Python:

1. While there is no quick fix to this problem, one thing that you need to keep in mind while trying to find a solution for the indentation error is the fact that you have to go through each line individually and find out which one contains the error.

In Python, all the lines of code are arranged according to blocks, so it becomes easier for you to spot an error. For example, if you have used the if statement in any line, the next line must definitely have an indentation.

Take a look at the example below.

If you need guidance on how the correct form of indentation will look like, take a look at the example below.

2. Go to your code editor settings and enable the option that seeks to display tabs and whitespaces. With this feature enabled, you will see single small dots, where each dot represents a tab/white space. If you notice a drop is missing where it shouldn’t be, then that line probably has an indentation error.

For Pycharm, please go to file — settings — editor — code style — python

3. Use the Python interpreter built-in Indent Guide. It takes you through each line and shows you exactly where your error lies, it is the surest way to find and fix all errors.

Conclusion:

Getting errors are inevitable part of programming, so is debugging. One cannot ignore indentation error while working with python but above tips show that it can be easily resolved. Hope this information makes your life little easy and programming journey more exciting.

In this post , we will see How to Fix Various Indentation Errors in Python.

Spacing is important in Python since the coding is dependent of the place or line where a code block starts or ends. Hence Indentation is crucial in Python coding.

P.S. – Once you read this post , go through our earlier post for extra tips –How To Fix – Indentation Problem in Python ? 


if( aicp_can_see_ads() ) {

}

Let us see the various types of Indentation Errors in Python –

1. IndentationError: unexpected indent –

Consider the example below –

>>>    print "hello world"
IndentationError: unexpected indent

The reason for this is the “EXTRA SPACE” before the command “print”

Fix –


if( aicp_can_see_ads() ) {

}

  • Check if  spaces mixed in with your tabs. Try doing a search & replace to replace all tabs with a few spaces.
  • Remove Extra Spaces
    Better to use Spaces than Tabs.
  • For Sublime Text users –  Set Sublime Text to use tabs for indentation: View –> Indentation –> Convert Indentation to Tabs . Uncheck the Indent Using Spaces option as well in the same sub-menu above.
  • For  Notepad++ , Change Tab Settings to 4 spaces
    Go to Settings -> Preferences -> Tab Settings -> Replace by spaces

2. IndendationError: Unindent does not match any outer indentation level –

This happens when Python cannot decide whether a specific statement belongs to a specific Code-Block or Not (due to Indentation – might be copy-paste code).

For instance, in the following, is the final print supposed to be part of the if clause, or not?

Example Below –


if( aicp_can_see_ads() ) {

}

>>> if acc_name == "NYC":
...   print "New York Region !"
... print "Where do I belong ?"
IndendationError: unindent does not match any outer indentation level

Fix

  • Check if  spaces mixed in with your tabs. Try doing a search & replace to replace all tabs with a few spaces.
  • Remove Extra Spaces
  • Better to use Spaces than Tabs.
  • For Sublime Text users –  Set Sublime Text to use tabs for indentation: View –> Indentation –> Convert Indentation to Tabs . Uncheck the Indent Using Spaces option as well in the same sub-menu above.
  • For  Notepad++ , Change Tab Settings to 4 spaces
    Go to Settings -> Preferences -> Tab Settings -> Replace by spaces

3. IndentationError: expected an indented block –

Normally occurs when a code block (if/while/for statement , function block etc.) , does not have spaces.  See example below –


if( aicp_can_see_ads() ) {

}

This line of code has the same number of spaces at the start as the one before, but the last line was expected to start a block (e.g. if/while/for statement, function definition).

>>> def foo():
... print "hello world"
IndentationError: expected an indented block

Fix


if( aicp_can_see_ads() ) {

}

  • Check if  spaces mixed in with your tabs. Try doing a search & replace to replace all tabs with a few spaces.
  • Remove Extra Spaces
    Better to use Spaces than Tabs.
  • For Sublime Text users –  Set Sublime Text to use tabs for indentation: View –> Indentation –> Convert Indentation to Tabs . Uncheck the Indent Using Spaces option as well in the same sub-menu above.
  • For  Notepad++ , Change Tab Settings to 4 spaces
    Go to Settings -> Preferences -> Tab Settings -> Replace by spaces

Hope this helps .

Home > Data Science > Indentation Error in Python: Causes, How to Solve, Benefits

As an interpreted, high-level and general-purpose programming language, Python increasingly garners accolades as the programming world’s most promising, leading and emerging platforms. Python is nothing without its ingenious design philosophy.

A key characteristic is an emphasis drawn to the notable use of significant indentation to enhance code-readability. The illustration highlighted below briefly outlines Python’s design philosophy’s bulwarks as twenty aphorisms, alluded to by Tim Peters, long-term Pythoneer, who eventually became one of Python’s most prolific and tenacious core developers. 

A Brief Introduction to Python

Before we delve into the specific technicalities underlying the indentation error in Python, we must get acquainted with Python’s fundamentals and the need for indentation. Doing so will not only help you gain a better appreciation of the error itself but offer an insight into the advantages that programmers gain by effectively choosing to resolve the same.

The inception of Python as a multi-paradigm programming language can be traced back to the year 1991. Since then, programmers have continually adapted Python’s core wireframe to suit a range of user-specific needs, such as data science and web and mobile development. 

Now, we all know that attempting to comprehend illegible handwriting is painstakingly tricky and often infuriating. Similarly, an unreadable and unstructured code is plain and simple, unacceptable in the programming world. This is where the notion of PEP or Python Enhancement Proposal comes to the programmer’s rescue. PEP to the Python Community is akin to a shared Google Doc for the general populace.

It is a continually updated descriptive mandate that keeps the Python programming community comprehensively informed of features and updates to improve code readability. By Guido van Rossum, Barry Warsaw and Nick Coghlan in 2001, the PEP 8 is referred to as Python’s style code.

What is Indentation?

It is primarily known that Python is a procedural language, and therefore, an indentation in Python is used to segregate a singular code into identifiable groups of functionally similar statements. The majority of the programming languages, including C, C++ and JAVA, employ curly braces’ {}’ to define a code block. Python marks a deviation from this design and prefers the use of indentation. 

Syntax of Indentation

According to the conventions outlined by PEP 8 whitespace ethics, every new iteration (i.e., a block of code) should start with an indentation, and the ending of the code should be the first line that is not indented. The common practice to execute an indentation is four white spaces or a single tab character, with areas being largely preferred over tabs.

As discussed earlier, the leading whitespaces at the start of a line determine the line’s indentation level. To group the statements for a particular code block, you will have to increase the indent level. Similarly, to close the grouping, you will have to reduce the indent level.

Causes of Indentation Error in Python

The ‘Indentation Error: Expected an indented block’ does not discriminate between users. Whether you are a novice at Python programming or an experienced software developer, this is bound to happen at some point in time. In Python, since all the code you type is arranged via correct whitespaces, if at any instance in the code, you have an incorrect indentation, the overall code with not run, and the interpreter will return an error function. To know exactly what to keep an eye out for, the following lists some of the common causes of an indentation error in Python:

1. The simultaneous use of tabs and space while coding. It can be argued that in theory, both tabs and spaces serve the same purpose, but let us consider this from the perspective of the interpreter. If white spaces and tabs are used inconsistently and interchangeably, it creates ambiguity. This will result in the interpreter getting confused between which alteration to use and eventually returning an indentation error in Python.

2. You have unintentionally placed an indentation in the wrong place or an absence of tabs or white spaces between code lines. Since Python adheres to strict guidelines to arrange written codes, an indentation in the wrong place will inevitably return an error. For example, the first line of Python should not be indented. 

3. Occasionally, while finishing an overdue, exceptionally long program, you might unknowingly miss out on indenting compound statement functions such as for, while and if. This will again lead to an indentation error. This is the most basic need for indentation when using Python and needs to be rigorously practised to master.

4. If you have forgotten to use indentation when working with user-defined functions or different classes, an error is likely to pop up.

How to solve an indentation error in Python?

1. Check for wrong white spaces or tabs. Unfortunately, there is no quick fix to an indentation error. Since the code is yours, the fact remains that you will have to assess each line to identify erroneous instances individually. However, since lines of code are arranged in blocks, the process is relatively simple. For example, if you have used the ‘if’ statement in a particular sequence, you can cross-check if you have remembered to indent the following line.

2. Be certain that the indentation for a specific block remains the same throughout the code, even if a new block is introduced in the middle. Check for inconsistencies in the indentation.

If the above manual solutions did not work for you, and you are having a hard time figuring out where you missed the indentation, then follow these steps:

3. Go to your code editor settings and enable the option that seeks to display tabs and whitespaces. With this feature enabled, you will see single small dots, where each dot represents a tab/white space. If you notice a drop is missing where it shouldn’t be, then that line probably has an indentation error.

4. Use the Python interpreter built-in Indent Guide. Arguably, this method is highly inefficient for several code lines. However, since it takes you through each line and shows you exactly where your error lies, it is the surest way to find and fix all errors.

Benefits of Indentation

Readability and consistency are essential for any good code. Following the PEP 8 whitespace, ethics should thus be non-negotiable. It logically substantiates your code, thereby contributing to a more pleasant coding experience. Additionally, if you follow this stylistic guideline where readability is your de facto, people who are unknown to you, but are interested in your work, will understand your code with ease. 

Disadvantages of Indentation              

  • If the code is large and the indentation is corrupted, it can be tedious to fix indentation errors. This is usually when a code is copying from an online source, Word document or PDF file. 
  • Popular programming languages typically use braces for indentation. For programmers just beginning to use Python, adjusting to the idea of using whitespaces for indentation can be difficult.

Summing Up

All that lies between you and a well-written code is an indentation, and all that lies between you, your well-written code and its seamless execution is an indentation error. Now, all humans make mistakes. All programmers are humans. Therefore, all programmers make mistakes. But an indentation error can easily be resolved. All you need to do is breathe and take your space.

What errors can I get due to indentation in Python?

Python determines when code blocks begin and stop by looking at the space at the beginning of the line. You may encounter the following Indentation errors:
1. Unexpected indent — This line of code has more spaces at the beginning than the one before it, but the one before it does not begin a subblock. In a block, all lines of code must begin with the same string of whitespace.
2. Unindent does not correspond to any of the outer indentation levels — This line of code contains less spaces at the beginning than the previous one, but it also does not match any other block.
3. An indented block was expected — This line of code begins with the same number of spaces as the previous one, yet the previous line was supposed to begin a block (e.g., if/while/for statement, function definition).

How do you fix inconsistent tabs and spaces in indentation Spyder?

Tabs and spaces are two separate characters that appear on the screen as whitespace. The issue is that there is no consensus on how big a tab character should be, thus some editors display it as taking up 8 spaces, others as 4 spaces, and others as 2, and it’s also customizable.
When you code but one line is indented with a tab and the other with spaces, Python throws an error, despite the fact that it seems good in the editor (but it won’t look fine if you double the width of a tab; now the tab lines will be indented two levels).
To avoid this problem, go to your text editor’s options and enable the convert tabs to spaces feature, which replaces the tab character with n space characters, where n is the tab width your editor uses.

How do you show indents on Spyder?

Select your code and press Tab or Shift + Tab to indent or un-indent it. Other tools for altering your code can be found in the Edit section.
