How to Create a Python Package

We'll cover the following...

The main difference between a module and a package is that a package is a collection of modules AND it has an __init__.py file. Depending on the complexity of the package, it may have more than one __init__.py. Let’s take a look at a simple folder structure to make this more obvious, then we’ll create some simple code to follow the structure we define.

Python
