Python Programming Basics

The Python language provides features common to many languages and allows add-on modules to be written to provide more specific functionality. Python 2 was used for many years and is still in use. Python 3 is newer and is being phased in as developers update their code.

Program Files and Modules

Python program files have the file extension .py. Python files correspond to modules that can have a hierarchical package naming convention. Python files can include built-in Python language and calls to built-in modules, and can also call add-on modules.
