Fix the 'str' object is not callable error in Python

In this tutorial, we are going to learn how to fix the TypeError: ‘str’ object is not callable in Python.

This error occurs for one of the following reasons:

1. If you try to use an str() built-in function as a variable name.

2. Using the parenthesis () instead of square brackets [] to access the characters from a string at a specific index.

Example:

str = 'Hello' # using str as a variable name

print(str(2)) # using parenthesis to access characters

Output:

TypeError:'str' object is not callable

To fix the error, use the square brackets [] syntax to access the characters from a list, and do not use the str keyword as a variable name because it is reserved for the str() function in python.

Here is an example:

greet = 'Hello'

print(greet[0]) # H'
print(greet[2]) # 'e'

Another cause of the error is calling the string value like a function :

greet_str = 'Hello'

# TypeError: 'str' object is not callable
print(greet_str())

Conclusion

The “str” object is not a callable error that occurs when we try to use the str as a variable name and using the parenthesis () to access the characters from a string. To fix the error always use the square brackets [] to access the characters at a specific index eg: user_str[1] and do not use the str() built-in keyword as a variable name because it is reserved for str() function in python.
