Solve – TypeError: ‘list’ object is not callable in Python

Solve – TypeError: ‘list’ object is not callable in Python #

The Python “TypeError: ‘list’ object is not callable” occurs when we try to call a list as a function using parenthesis () . To solve the error, make sure to use square brackets when accessing a list at a specific index, e.g. my_list[0] .

Here is one example of how the error occurs.

main.py Copied! my_list = [ ‘a’ , ‘b’ , ‘c’ ] print ( my_list ( 0 ) )

The issue in the code sample is that we used parenthesis instead of square brackets when accessing the list at a specific index.

main.py Copied! my_list = [ ‘a’ , ‘b’ , ‘c’ ] print ( my_list [ 0 ] ) print ( my_list [ 1 ] )

Another thing to look out for is that you’re not overriding the built-in list() function.

main.py Copied! list = [ ‘a’ , ‘b’ , ‘c’ ] print ( list ( [ 1 , 2 , 3 ] ) )

To solve the error in this situation, rename your variable and restart your script.

main.py Copied! my_list = [ ‘a’ , ‘b’ , ‘c’ ] print ( list ( [ 1 , 2 , 3 ] ) )

Another common cause of the error is simply trying to call a list as a function.

main.py Copied! my_list = [ ‘a’ , ‘b’ , ‘c’ ] print ( my_list ( ) )

To solve the error, you either have to remove the parenthesis or figure out how the variable got assigned a list instead of a function or a class.

The error is also caused when we have a class method and a class property with the same name.

main.py Copied! class Employee ( ) : def __init__ ( self , tasks ) : self . tasks = tasks def tasks ( self ) : return self . tasks emp = Employee ( [ ‘dev’ , ‘test’ ] ) print ( emp . tasks ( ) )

The Employee class has a method and an attribute with the same name.

The attribute hides the method, so when we try to call the method on an instance of the class, we get the object is not callable error.

To solve the error, you have to rename the class method.

main.py Copied! class Employee ( ) : def __init__ ( self , tasks ) : self . tasks = tasks def get_tasks ( self ) : return self . tasks emp = Employee ( [ ‘dev’ , ‘test’ ] ) print ( emp . get_tasks ( ) )

Once you rename the method, you will be able to call it without any issues.

Make sure you don’t have a function and a variable with the same name.

main.py Copied! def example ( ) : return ‘hello world’ example = [ ‘a’ , ‘b’ , ‘c’ ] print ( example ( ) )

The example variable shadows the function with the same name, so when we try to call the function, we actually end up calling the variable.

Renaming the variable or the function solves the error.

Typeerror: ‘list’ Object is Not Callable [Solved]

The most common scenario where Python throws TypeError: ‘list’ object is not callable is when you have assigned a variable name as “list” or if you are trying to index the elements of the list using parenthesis instead of square brackets.

In this tutorial, we will learn what ‘list’ object is is not callable error means and how to resolve this TypeError in your program with examples.

Python TypeError: ‘list’ object is not callable

There are two main scenarios where you get a ‘list’ object is not callable error in Python. Let us take a look at both scenarios with examples.

Scenario 1 – Using the built-in name list as a variable name

The most common mistake the developers tend to perform is declaring the Python built-in names or methods as variable names.

What is a built-in name?

In Python, a built-in name is nothing but the name that the Python interpreter already has assigned a predefined value. The value can be either a function or class object.

The Python interpreter has 70+ functions and types built into it that are always available.

In Python, a list is a built-in function, and it is not recommended to use the built-in functions or keywords as variable names.

Python will not stop you from using the built-in names as variable names, but if you do so, it will lose its property of being a function and act as a standard variable.

Let us take a look at a simple example to demonstrate the same.

fruit = “Apple” list = list(fruit) print(list) car=”Ford” car_list=list(car) print(car_list)

Output

[‘A’, ‘p’, ‘p’, ‘l’, ‘e’] Traceback (most recent call last): File “c:\Personal\IJS\Code\main.py”, line 6, in car_list=list(car) TypeError: ‘list’ object is not callable

If you look at the above example, we have declared a fruit variable, and we are converting that into a list and storing that in a new variable called “ list “.

Since we have used the “ list ” as a variable name here, the list() method will lose its properties and functionality and act like a normal variable.

We then declare a new variable called “ car “, and when we try to convert that into a list by creating a list, we get TypeError: ‘list’ object is not callable error message.

The reason for TypeError is straightforward we have a list variable that is not a built function anymore as we re-assigned the built-in name list in the script. This means you can no longer use the predefined list value, which is a class object representing the Python list.

Solution for using the built-in name list as a variable name

If you are getting object is not callable error, that means you are simply using the built-in name as a variable in your code.

fruit = “Apple” fruit_list = list(fruit) print(fruit_list) car=”Ford” car_list=list(car) print(car_list)

Output

[‘A’, ‘p’, ‘p’, ‘l’, ‘e’] [‘F’, ‘o’, ‘r’, ‘d’]

In our above code, the fix is simple we need to rename the variable “list” to “fruit_list”, as shown below, which will fix the ‘list’ object is not callable error.

Scenario 2 – Indexing list using parenthesis()

Another common cause for this error is if you are attempting to index a list of elements using parenthesis() instead of square brackets []. The elements of a list are accessed using the square brackets with index number to get that particular element.

Let us take a look at a simple example to reproduce this scenario.

my_list = [1, 2, 3, 4, 5, 6] first_element= my_list(0) print(” The first element in the list is”, first_element)

Output

Traceback (most recent call last): File “c:\Personal\IJS\Code\tempCodeRunnerFile.py”, line 2, in first_element= my_list(0) TypeError: ‘list’ object is not callable

In the above program, we have a “ my_list ” list of numbers, and we are accessing the first element by indexing the list using parenthesis first_element= my_list(0) , which is wrong. The Python interpreter will raise TypeError: ‘list’ object is not callable error.

Solution for Indexing list using parenthesis()

The correct way to index an element of the list is using square brackets. We can solve the ‘list’ object is not callable error by replacing the parenthesis () with square brackets [] to solve the error as shown below.

my_list = [1, 2, 3, 4, 5, 6] first_element= my_list[0] print(” The first element in the list is”, first_element)

Output

The first element in the list is 1

Conclusion

The TypeError: ‘list’ object is not callable error is raised in two scenarios

If you try to access elements of the list using parenthesis instead of square brackets If you try to use built-in names such as list as a variable name

Most developers make this common mistake while indexing the elements of the list or using the built-in names as variable names. PEP8 – the official Python style guide – includes many recommendations on naming variables properly, which can help beginners.

TypeError: ‘list’ object is not callable in python

Before you can fully understand what the error means and how to solve, it is important to understand what a built-in name is in Python.

What is a built-in name?

In Python, a built-in name is a name that the Python interpreter already has assigned a predefined value. The value can be either a function or class object. These names are always made available by default, no matter the scope. Some of the values assigned to these names represent fundamental types of the Python language, while others are simple useful.

As of the latest version of Python – 3.6.2 – there are currently 61 built-in names. A full list of the names and how they should be used, can be found in the documentation section Built-in Functions.

An important point to note however, is that Python will not stop you from re-assigning builtin names. Built-in names are not reserved, and Python allows them to be used as variable names as well.

Here is an example using the dict built-in:

>>> dict = {} >>> dict {} >>>

As you can see, Python allowed us to assign the dict name, to reference a dictionary object.

What does “TypeError: ‘list’ object is not callable” mean?

To put it simply, the reason the error is occurring is because you re-assigned the builtin name list in the script:

list = [1, 2, 3, 4, 5]

When you did this, you overwrote the predefined value of the built-in name. This means you can no longer use the predefined value of list , which is a class object representing Python list.

Thus, when you tried to use the list class to create a new list from a range object:

myrange = list(range(1, 10))

Python raised an error. The reason the error says “‘list’ object is not callable”, is because as said above, the name list was referring to a list object. So the above would be the equivalent of doing:

[1, 2, 3, 4, 5](range(1, 10))

Which of course makes no sense. You cannot call a list object.

How can I fix the error?

Suppose you have code such as the following:

list = [1, 2, 3, 4, 5] myrange = list(range(1, 10)) for number in list: if number in myrange: print(number, ‘is between 1 and 10’)

Running the above code produces the following error:

Traceback (most recent call last): File “python”, line 2, in TypeError: ‘list’ object is not callable

If you are getting a similar error such as the one above saying an “object is not callable”, chances are you used a builtin name as a variable in your code. In this case and other cases the fix is as simple as renaming the offending variable. For example, to fix the above code, we could rename our list variable to ints :

ints = [1, 2, 3, 4, 5] # Rename “list” to “ints” myrange = list(range(1, 10)) for number in ints: # Renamed “list” to “ints” if number in myrange: print(number, ‘is between 1 and 10’)

PEP8 – the official Python style guide – includes many recommendations on naming variables.

This is a very common error new and old Python users make. This is why it’s important to always avoid using built-in names as variables such as str , dict , list , range , etc.

Many linters and IDEs will warn you when you attempt to use a built-in name as a variable. If your frequently make this mistake, it may be worth your time to invest in one of these programs.

I didn’t rename a built-in name, but I’m still getting “TypeError: ‘list’ object is not callable”. What gives?

Another common cause for the above error is attempting to index a list using parenthesis ( () ) rather than square brackets ( [] ). For example:

>>> lst = [1, 2] >>> lst(0) Traceback (most recent call last): File ““, line 1, in lst(0) TypeError: ‘list’ object is not callable

For an explanation of the full problem and what can be done to fix it, see TypeError: ‘list’ object is not callable while trying to access a list.
