Solve - list object is not callable error in Python

In this tutorial, we will learn how to solve the TypeError: ‘list’ object is not callable in Python.

This error occurs for one of the following reasons:

  1. If you try to use a list keyword as a variable name.

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

Here is an example of how the error occurs:

price_list = [10, 20, 30]

# using parenthesis for accessing data
print(price_list(1))

Output:

Traceback (most recent call last):
  File "main.py", line 13, in <module>
    print(price_list(1))
TypeError: 'list' object is not callable

In the above example , we are getting the error because we are using the () to access the data from a list instead of [] square brackets.

To solve the error, use the square brackets [] syntax to access the elements from a list.

Here is an example:

price_list = [10, 20, 30]

print(price_list[1]) # 20
print(price_list[2]) # 30

Note: The list is an object data type in Python.

Another common cause of the error is using the built-in list() function as a variable name in Python.

Here is an example:

# overiding the built-in list() function
list = [10, 20, 30]

# creating a list using list() function
fruits_list = list(['apple', 'banana', 'cherry'])
print(fruits_list)

Output:

Traceback (most recent call last):
  File "main.py", line 14, in <module>
    fruits_list = list(['apple', 'banana', 'cherry'])
TypeError: 'list' object is not callable

To Solve the error, change the variable name to someother and re-run the code.

# not overiding the built-in list() function
price_list = [10, 20, 30]

fruits_list = list(['apple', 'banana', 'cherry'])
print(fruits_list)

and do not use the list keyword as a variable name because it is reserved for list() function in python

Conclusion

The “list” object is not callable error occurs, when we try to call a list object as a python function using the parenthesis (). To solve the error, use the square brackets [] to access the data at a specific index eg: price_list[1] and do not use the list built-in keyword as a variable name because it is reserved for list() function in python.
