TypeError: int object is not subscriptable

The error message "int object is not subscriptable" typically occurs in Python when you try to use the square bracket notation to access a particular element of an integer (or any other non-indexable data type).

An Example Scenario

Following is an example to illustrate this error:

x = 123 print(x[0])

When you run this code, you'll get the following error message:

TypeError: 'int' object is not subscriptable

This error message means that you can't use the square bracket notation to access a particular element of the integer 'x', because integers are not indexable or subscriptable.

How to fix: 'int' object is not subscriptable

Following are some ways to fix this error:

Convert the integer to a string:

If you want to access a specific digit of an integer, you can convert the integer to a string using the str() function and then use square bracket notation to access the desired digit.

x = 123 digit = int(str(x)[0]) print(digit) #Output:1

Check that you are using the correct data type:

Make sure that the variable you are trying to access with square brackets is an indexable data type such as a list, tuple, or string.

my_list = [1, 2, 3, 4, 5] if type(my_list) == list: print("my_list is a list datatype") else: print("Error: my_list is not a list")

Check that you are not trying to access an index that doesn't exist:

If you are trying to access an index of a list or tuple, make sure that the index you are trying to access actually exists in the list or tuple.

my_list = [1, 2, 3, 4, 5] if len(my_list) >= 7: print("Index 7 exists") print("Value at index 7:", my_list[7]) else: print("Index 7 does not exist") #Output:Index 7 does not exist

Use conditional statements:

If you want to access a specific element of a list or tuple based on a condition, use conditional statements instead of square bracket notation.

my_list = [1, 2, 3, 4, 5] if 3 in my_list: index = my_list.index(3) print("Index of 3:", index) else: print("3 not found in list") # Output: Index of 3: 2

By following these steps, you can fix the "int object is not subscriptable" error in Python.

Subscriptable objects in Python

In Python, subscriptable objects are those that can be accessed using the square bracket notation. These include:

Lists:

A list is a collection of items, which can be of any data type, and are enclosed in square brackets []. Items in a list can be accessed using the square bracket notation and an index.

Tuples:

A tuple is similar to a list, but it is immutable (cannot be changed) and is enclosed in parentheses (). Items in a tuple can be accessed using the square bracket notation and an index.

Strings:

A string is a collection of characters, enclosed in either single or double quotes. Characters in a string can be accessed using the square bracket notation and an index.

Dictionaries:

A dictionary is a collection of key-value pairs, enclosed in curly braces {}. Values in a dictionary can be accessed using the square bracket notation and a key.

Sets:

A set is a collection of unique items, enclosed in curly braces {}. Items in a set cannot be accessed using an index, but some set operations like "in" or "not in" can be used to check for the presence of an item.

Subscriptable objects are an important concept in Python and are used frequently in programming to access and manipulate data.
