Object is not subscriptable python error

Typeerror: type object is not subscriptable error occurs while accessing type object with index. Actually only those python objects which implements __getitems__() function are subscriptable. In this article, we will first see the root cause for this error. We will also explore how practically we can check which object is subscriptable and which is not. At last but not least, we will see some real scenarios where we get this error. So let’s start the journey.

Typeerror: type object is not subscriptable ( Fundamental Cause) –

The root cause for this type object is not subscriptable python error is invoking type object by indexing. Let’s understand with some practical scenarios.

var_list=[1,2,3]
var=type(var_list)
var[0]

Here var is a type python object. In the place of same, the list is python subscriptable object. Hence we can invoke it via index. Moreover, Here is the implementation –

var_list=[1,2,3]
var=type(var_list)
var_list[0]

The best way to fix this error is using correct object for indexing. Let’s understand with one example.

The fix is calling var[0] in the place of var_type[0] . Here ‘var’ is the correct object. It is a ‘str’ type object which is subscriptible python object.

How to check python object is subscriptable ?

Most importantly, As I explained clearly, Only those object which contains __getitems__() method in its object ( blueprint of its class) is subscriptible. Let’s see any subscriptible object and its internal method-

print(dir(var))

The output is –

['__add__', '__class__', '__contains__', '__delattr__', '__dir__',
 '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__',
 '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', 
'__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', 
'__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'capitalize', 'casefold',
 'center', 'count', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'format_map', 'index', 
'isalnum', 'isalpha', 'isascii', 'isdecimal', 'isdigit', 'isidentifier', 'islower', 'isnumeric', 
'isprintable', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans',
 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 
'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill']

Firstly, As the internal method __getitem__() is available in the implementation of the object of var( list) hence it is subscriptible and that is why we are not getting any error while invoking the object with indexes. Hope this article is helpful for your doubt.

Introduction

Some of the objects in python are subscriptable. This means that they hold and hold other objects, but an integer is not a subscriptable object. We use Integers used to store whole number values in python. If we treat an integer as a subscriptable object, it will raise an error. So, we will be discussing the particular type of error that we get while writing the code in python, i.e., TypeError: ‘int’ object is not subscriptable. We will also discuss the various methods to overcome this error.

What is TypeError?

The TypeError occurs when you try to operate on a value that does not support that operation. Let us understand with the help of an example:

Suppose we try to concatenate a string and an integer using the ‘+’ operator. Here, we will see a TypeError because the + operation is not allowed between the two objects that are of different types.

#example of typeError

S = "Latracal Solutions"
number = 4
print(S + number)

Output:

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    print(S + number)
TypeError: can only concatenate str (not "int") to str

Explanation:

Here, we have taken a string ‘Latracal Solutions” and taken a number. After that, in the print statement, we try to add them. As a result: TypeError occurred.

What is ‘int’ object is not subscriptable?

When we try to concatenate string and integer values, this message tells us that we treat an integer as a subscriptable object. An integer is not a subscriptable object. The objects that contain other objects or data types, like strings, lists, tuples, and dictionaries, are subscriptable. Let us take an example :

1. Number: typeerror: ‘int’ object is not subscriptable

#example of integer which shows a Typeerror

number = 1500
print(number[0])

output:

Traceback (most recent call last):
  File "<pyshell#7>", line 1, in <module>
    print(number[0])
TypeError: 'int' object is not subscriptable

Explanation:

Here, we have taken a number and tried to print the through indexing, but it shows type error as integers are not subscriptable.

2. List: typeerror: ‘int’ object is not subscriptable

This TyperError problem doesn’t occur in the list as it is a subscriptable object. We can easily perform operations like slicing and indexing.

#list example which will run correctly

Names = ["Latracal" , " Solutions", "Python"]
print(Names[1])

Output:

Solutions

Explanation:

Here firstly, we have taken the list of names and accessed it with the help of indexing. So it shows the output as Solutions.

Daily Life Example of How typeerror: ‘int’ object is not subscriptable can Occur

Let us take an easy and daily life example of your date of birth, written in date, month, and year. We will write a program to take the user’s input and print out the date, month, and year separately.

#Our program begins from here

Date_of_birth = int(input("what is your birth date?"))

birth_date = Date_of_birth[0:2]

birth_month = Date_of_birth[2:4]

birth_year = Date_of_birth[4:8]

print(" birth_date:",birth_date)
print("birth_month:",birth_month)
print("birth_year:",birth_year)

Output:

what is your birth date?31082000
Traceback (most recent call last):
  File "C:/Users/lenovo/Desktop/fsgedg.py", line 3, in <module>
    birth_date = Date_of_birth[0:2] 
TypeError: 'int' object is not subscriptable

Explanation:

Here firstly, we have taken the program for printing the date of birth separately with the help of indexing. Secondly, we have taken the integer input of date of birth in the form of a date, month, and year. Thirdly, we have separated the date, month, and year through indexing, and after that, we print them separately, but we get the output ad TypeError: ‘int’ object is not subscriptable. As we studied above, the integer object is not subscriptable.

Solution of TypeError: ‘int’ object is not subscriptable

We will make the same program of printing data of birth by taking input from the user. In that program, we have converted the date of birth as an integer, so we could not perform operations like indexing and slicing.

To solve this problem now, we will remove the int() statement from our code and run the same code.

#remove int() from the input()

Date_of_birth = input("what is your birth date?")

birth_date = Date_of_birth[0:2]

birth_month = Date_of_birth[2:4]

birth_year = Date_of_birth[4:8]

print(" birth_date:",birth_date)
print("birth_month:",birth_month)
print("birth_year:",birth_year)

Output:

what is your birth date?31082000
 birth_date: 31
birth_month: 08
birth_year: 2000

Explanation:

Here, we have just taken the input into the string by just removing the int(), and now we can do indexing and slicing in it easily as it became a list that is subscriptable, so no error arises.

Conclusion: Typeerror: ‘int’ object is not subscriptable

We have learned all key points about the TypeError: ‘int’ object is not subscriptable. There are objects like list, tuple, strings, and dictionaries which are subscriptable. This error occurs when you try to do indexing or slicing in an integer.

Suppose we need to perform operations like indexing and slicing on integers. Firstly, we have to convert the integer into a string, list, tuple, or dictionary.

Now you can easily the solve this python TypeError like an smart coder.

Happy Pythoning!

◈ Introduction

In this article, we will be discussing certain type of error in Python. To be more specific we will be discussing the reason behind the occurrence of : TypeError: 'int' Object Is Not Subscriptable in Python and the methods to overcome such errors.

Let’s have a look at an example which demonstrates the occurrence of such errors.

Example: Consider the following program:

Output:

If you have come across a similar bug/error, then it must have been really frustrating! 😩

But it also brings us to a list of questions:

• What does object not Subscriptable mean?
• What is a TypeError?
• What is TypeError:'int' object is not subscriptable ?
• How do I fix: TypeError:'int' object is not subscriptable ?

Hence, without further delay let us discover the answers to our questions and then solve our problem.

➥ What Does Object Not Subscriptable Mean?

In simple terms, a subscriptable object in Python is an object that can contain other objects, i.e., the objects which are containers can be termed as subscriptable objects. Strings, tuples, lists and dictionaries are examples of subscriptable objects in Python.

➟ Why is Integer not a subscriptable Object?

Integers are whole numbers. They cannot contain other objects within them. Further, subscriptable objects implement the __getitem__() method and integer objects do not implement the __getitem__() method.

A TypeError is raised when a certain operation is applied to an object of an incorrect type. For example, if you try to add a string object and an integer object using the + operator, then you will encounter a TypeError because the + operation is not allowed between the two objects that are f different types.

Example:

Output:

➥ What is: TypeError:’int’ object is not subscriptable?

• You will encounter TypeError: object is not subscriptable in Python when you try to use indexing on an object that is not subscriptable.
• Since integer is not a subscriptable object, thus if you try to use indexing upon an integer object then Python will throw the following error: TypeError:'int' object is not subscriptable.

That brings us to our next questions:- What are some of the scenarios where we come across TypeError:'int' object is not subscriptable and how can we fix it?

To answer the above questions, let us visualize the occurrence and solution to this kind of TypeError with help of examples.

✨ Scenario 1: Trying To Access Index Of An Integer Object

We have already discussed the problem statement in the introduction section of this article where we tried to find the sum of all the digits of a three-digit number.

However, we got TypeError: object is not subscriptable in our futile attempt to derive the sum. The reason was: we treated the integer object num as a container object and tried to access it using its indices.

Now, it’s time to make amendments and make our program work! 😃

The Solution:

✯ Method 1: Convert Integer Object to a String Object

A simple solution to our problem is:

• accept the user input num as a string,
• Each digit can now be accessed using their index now as they are strings. Typecast each digit string to an integer and calculate the sum.

Output:

✯ Method 2: Overwrite the __getitem__ Method

Another approach to solving the non-subscriptable TypeError is to redefine the __getitem__ method in the code itself as shown below:

Output:

Explanation:

In this case, we defined the __getitem__ method in our code and made it return each digit of the three-digit number in the form of an integer.

✨ Scenario 2: Treating an Integer as a List

Given below is another scenario which raises – TypeError:'int' object is not subscriptable.

Output:

In the above program, price is an integer value, however we tried to use it as a list by using its index. Thus we got the error!

The Solution:

The solution is pretty straightforward in this case. You just have to avoid using the integer object as a container type object.

Output:

Conclusion

We learned some key points about how to deal with TypeError:'int' object is not subscriptable in Python. To avoid these errors in your code, remember:

Python raises TypeError: object is not subscriptable if you use indexing, i.e., the square bracket notation with a non-subscriptable object . To fix it you can:

• wrap the non-subscriptable objects into a container data type as a string, list, tuple or dictionary, or,
• by removing the index call, or
• by defining the __getitem__ method in your code.
