How To Make A Python Module

Python modules are reusable pieces of code that can be imported and used in other programs. Creating a module can make programming more efficient and organized. In this tutorial, we will go through the steps of creating a Python module.

Step 1: Writing the Python Code

The first step is to write the Python code that will make up our module. This code can be written in any text editor or Python IDE. Let’s create a simple module that will contain a function to calculate the area of a rectangle.

Save this code in a file named

Step 2: Creating the File

To create a Python module, we need to create an file in the same directory as our Python code file. This file can be empty or can contain an initialization code for our module. In the case of our rectangle module, we will create an empty file.

To create an empty file, open a text editor and create a new file. Name the file and save it in the same directory as the file.

Step 3: Testing the Module

To test the module, we can create a new Python program that imports the module and uses its functions. Let’s create a test program that imports our rectangle module and uses the rectangle_area function.

Save this code in a file named and run it from the command line.

The area of the rectangle is: 50


In this tutorial, we learned how to create a Python module. We wrote the Python code for our module, created an file, and tested the module in a separate program. Now, we can import and use our module in other programs, making our code more efficient and organized.
