In simple words, a python module contains functions and statements. A module can contain many elements or define functions, classes, executable code, and variables as well. A module can help you to keep the related code collectively in someplace. In logical aspects as also you can keep your code organized. If you use any editors and shell, there will be some modules that are available by-default or in-built. So, we are going to look at many ways to get the list of python modules. Let’s roll!!!

Creating a simple python module

 Creating a python module is very easy. As discussed above, in a module you can define functions, classes, and even variables. You have to write the function or runnable code, save the file with .py extension, import, and use it in code. As simple as that. 

def welcome_message(name):
    print("Howdy" + name)

Well, we have defined a function that greets the input name. We have to save the file as a .py extension. In this case, we are going to save it as Now we can import the module and call the function.

import mymodule

Get list of modules in python (In-built)

Creating a module is easy as shown above. But python offers plenty of most useful modules for your coding purposes. If you want to know what are modules that python offers for you, you can run the below code to get the list of modules in python.

That’s it. The help command will get list of python module which are available to you to use in the code.

List of python modules in Conda environment

Do you use Anaconda navigator? If yes, then you have to open the conda prompt and then run the “conda list” command to get the list of available modules in python. 

conda list
conda list of modules in python

With the help of “conda list” command, you will get the list of modules with their current version and build information.

Benefits of Python modules

  • You can create a logically organized code with all related functions and statements in one file i.e. module.
  • It will increase the readability of the code for easy understanding.
  • The defined function can reusable when needed.
  • It will help to avoid the duplicity of the code.

Wrapping Up

Python by default offers many modules for your coding journey. You can easily create your custom modules based on your requirements. If you want, you can get the list of python modules with the help of code as shown above. You can use different methods as illustrated in this article. Happy python!!!.
