Modules

Modules are just files that contain Python statements and definitions. A file that contains Python code (for example, sample.py) is called a module and its module name would be sample. Using modules, we can break larger programs into small and organized ones. An important feature of a module is re-usability. Instead of copying the definitions of the most used functions in different programs, you can define them in the module and just import them whenever needed.

Let's create a module and import it. We will create two scripts: sample.py and add.py. We will import a sample module in our add.py. Now, save the following code as sample.py. Let's take a look with the following example:

sample.pydef addition(num1, num2): result = num1 + ...
