How to Import External Python Files and Functions Into Your Main Program!

This brief tutorial covers how to reference and import outside functions from .py python files in your local program directory! This is a super useful tool for creating large scale programs where subprograms and subfuctions and separated out into easy to read containers. We also cover how to alias those external files to shorten the name you need to access them.

Having problems navigating from main program to external functions file. Invariably, I get the "name "variable' is not defined when I execute the main program. I normally want to build lists in the function and pass it on to main. I declare the list in the function and assign the list as a global variable. Seems like I'm not defining the scope of the variables correctly. Could use your help. Thanks.

Why don't you use something like this?

import useless_programs as bad
import useful_programs as good
