Object is not callable python что это

What does "TypeError 'xxx' object is not callable" means?

As a starting developer in Python I’ve seen this error message many times appearing in my console but I don’t fully understand what does it means.

Could anyone tell me, in a general way, what kind of action produces this error?

That error occurs when you try to call, with () , an object that is not callable.

A callable object can be a function or a class (that implements __call__ method). According to Python Docs:

object.__call__(self[, args. ]): Called when the instance is “called” as a function

x is not a callable object, but you are trying to call it as if it were it. This example produces the error:

TypeError: module object is not callable [Python Error Solved]

Ihechikara Vincent Abba

In this article, we’ll talk about the «TypeError: ‘module’ object is not callable» error in Python.

We’ll start by defining some of the keywords found in the error message — module and callable .

You’ll then see some examples that raise the error, and how to fix it.

Feel free to skip the next two sections if you already know what modules are, and what it means to call a function or method.

What Is a Module in Programming?

In modular programming, modules are simply files that contain similar functionalities required to perform a certain task.

Modules help us separate and group code based on functionality. For example, you could have a module called math-ops.py which will only include code related to mathematical operations.

This makes easier to read, reuse, and understand the code. To use a module in a different part of your code base, you’d have to import it to gain access to all the functionalities defined in the module.

In Python, there are many built-in modules like os , math , time , and so on.

Here’s an example that shows how to use the math module:

As you can see above, the first thing we did before using the math module was to import it: import math .

We then made use of the module’s sqrt method which returns the square root of a number: math.sqrt(25) .

All it took us to get the square root of 25 was two lines of code. In reality, the math module alone has over 3500 lines of code.

This should help you understand what a module is and how it works. You can also create your own modules (we’ll do that later in this article).

What Does callable Mean in the “TypeError: module object is not callable” Error?

In Python and most programming languages, the verb «call» is associated with executing the code written in a function or method.

Other similar terms mostly used with the same action are «invoke» and «fire».

Here’s a Python function that prints «Smile!» to the console:

If you run the code above, nothing will be printed to the console because the function smile is yet to be called, invoked, or fired.

To execute the function, we have to write the function name followed by parenthesis. That is:

Without the parenthesis, the function will not be executed.

Now you should understand what the term callable means in the error message: «TypeError: ‘module’ object is not callable».

What Does the “TypeError: module object is not callable” Error Mean in Python?

The last two sections helped us understand some of the keywords found in the «TypeError: ‘module’ object is not callable» error message.

To put it simply, the «TypeError: ‘module’ object is not callable» error means that modules cannot be called like functions or methods.

How to Fix the “TypeError: module object is not callable” Error in Python

There are generally two ways that the «TypeError: ‘module’ object is not callable» error can be raised: calling an inbuilt or third party module, and calling a module in place of a function.

Error Example #1

In the example above, we called the math module (by using parenthesis () ) and passed 25 as a parameter hoping to perform a particular math operation: math(25) . But we got the error.

To fix this, we can make use of any math method provided by the math module. We’ll use the sqrt method:

Error Example #2

For this example, I’ll create a module for calculating two numbers:

The name of the module above is add which can be derived from the file name add.py.

Let’s import the add() function from the add module in another file:

You must be wondering why we’re getting the error even though we imported the module.

Well, we imported the module, not the function. That’s why.

To fix this, you have to specify the name of the function while importing the module:

We’re being specific: from add import add . This is the same as saying, «from the add.py module, import the add function».

You can now use the add() function in the main.py file.

Summary

In this article, we talked about the «TypeError: ‘module’ object is not callable» error in Python.

This error occurs mainly when we call or invoke a module as though it were a function or method.

We started by discussing what a module is in programming, and what it means to call a function – this helped us understand what causes the error.

We then gave some examples that showed the error being raised and how to fix it.

How to fix "‘list’ object is not callable" in Python

✋ Update: This post was originally published on my blog decodingweb.dev, where you can read the latest version for a �� user experience.

The “TypeError: ‘list’ object is not callable” error occurs when you try to call a list ( list object) as if it was a function!

Here’s what the error looks like:

Exit fullscreen mode

Calling a list object as if it’s a callable isn’t what you’d do on purpose, though. It usually happens due to a wrong syntax or overriding a function name with a list object.

Let’s explore the common causes and their solutions.

How to fix TypeError: ‘list’ object is not callable?

This TypeError happens under various scenarios:

1. Declaring a variable with a name that’s also the name of a function
2. Indexing a list by parenthesis rather than square brackets
3. Calling a method that’s also the name of a property
4. Calling a method decorated with @property

Declaring a variable with a name that’s also the name of a function: A Python function is an object like any other built-in object, such as str , int , float , dict , list , etc.

All built-in functions are defined in the builtins module and assigned a global name for easier access. For instance, list refers to the __builtins__.list function.

That said, overriding a function (accidentally or on purpose) with any value (e.g., a list object) is technically possible.

In the following example, we’ve declared a variable named list containing a list of numbers. In its following line, we try to create another list — this time by using the list() and range() functions:

Exit fullscreen mode

If you run the above code, Python will complain with a «TypeError: ‘list’ object is not callable» error because we’ve already assigned the list name to the first list object.

We have two ways to fix the issue:

1. Rename the variable list
2. Explicitly access the list() function from the builtins module ( __bultins__.list )

The second approach isn’t recommended unless you’re developing a module. For instance, if you want to implement an open() function that wraps the built-in open() :

Exit fullscreen mode

In almost every other case, you should always avoid naming your variables as existing functions and methods. But if you’ve done so, renaming the variable would solve the issue.

So the above example could be fixed like this:

Exit fullscreen mode

This issue is common with function names you’re more likely to use as variable names. Functions such as vars , locals , list , all , or even user-defined functions.

In the following example, we declare a variable named all containing a list of items. At some point, we call all() to check if all the elements in the list (also named all ) are True :

Exit fullscreen mode

Obviously, we get the TypeError because the built-in function all() is now shadowed by the new value of the all variable.

To fix the issue, we choose a different name for our variable:

Exit fullscreen mode

⚠️ Long story short, you should never use a function name (built-in or user-defined) for your variables!

Overriding functions (and calling them later on) is the most common cause of the «TypeError: ‘list’ object is not callable» error. It’s similar to calling integer numbers as if they’re callables.

Now, let’s get to the less common mistakes that lead to this error.

Indexing a list by parenthesis rather than square brackets: Another common mistake is when you index a list by () instead of [] . Based on Python semantics, the interpreter will see any identifier followed by a () as a function call. And since the parenthesis follows a list object, it’s like you’re trying to call a list.

As a result, you’ll get the «TypeError: ‘list’ object is not callable» error.

Exit fullscreen mode

This is how you’re supposed to access a list item:

Exit fullscreen mode

Calling a method that’s also the name of a property: When you define a property in a class constructor, it’ll shadow any other attribute of the same name.

Exit fullscreen mode

In the above example, since we have a property named authors , the method authors() is shadowed. As a result, any reference to authors will return the property authors , returning a list object. And if you call this list object value like a function, you’ll get the «TypeError: ‘list’ object is not callable» error.

The name get_authors sounds like a safer and more readable alternative:

Exit fullscreen mode

Calling a method decorated with @property decorator: The @property decorator turns a method into a “getter” for a read-only attribute of the same name. You need to access a getter method without parenthesis, otherwise you’ll get a TypeError.

Exit fullscreen mode

To fix it, you need to access the getter method without the parentheses:

Exit fullscreen mode

Alright, I think it does it! I hope this quick guide helped you fix your problem.

Object is not callable python что это

Python is well known for the different modules it provides to make our tasks easier. Not just that, we can even make our own modules as well., and in case you don’t know, any Python file with a .py extension can act like a module in Python.

In this article, we will discuss the error called “typeerror ‘module’ object is not callable” which usually occurs while working with modules in Python. Let us discuss why this error exactly occurs and how to resolve it.

Fixing the typerror module object is not callable error in Python

Since Python supports modular programming, we can divide code into different files to make the programs organized and less complex. These files are nothing but modules that contain variables and functions which can either be pre-defined or written by us. Now, in order to use these modules successfully in programs, we must import them carefully. Otherwise, you will run into the “typeerror ‘module’ object is not callable” error. Also, note that this usually happens when you import any kind of module as a function. Let us understand this with the help of a few examples.

Example 1: Using an in-built module

Look at the example below wherein we are importing the Python time module which further contains the time() function. But when we run the program, we get the typeerror. This happens because we are directly calling the time module and using the time() function without referring to the module which contains it.
