Create our own module in python and consume it

In this article, we will create our own module in python and consume it.

What is a module?

A module is the part of program that contains one or more routines.

Creating a module

To create a module

1. Open a new python file and save it as ‘MessageModule.py’ (you can give any name).

2. Write following code inside the module.

def PrintHelloWorldMessage():
  print("Hello world")
  return

For the sake of simplicity, you can create a module in the same folder as the calling program.

Calling a module

   1. Create a new Python file and name it as ‘caller.py’ (you can give any name).

   2. Inside the file, import module using the import keyword

   3. After you import the module, you can call the function using module name.function name.

import MessageModule
MessageModule.PrintHelloWorldMessage();
