Class Modules have to be in the working directory in order to be imported to a python program. However, I want to keep my individual main programs in separate directories based on use, and not have all programs and all classes jammed into one enormous directory.
What can I add to my scripts to point them to the correct module directory? Even better: can I make my module directory on a repo like GitHub and import for from there?
Python modules need to be somewhere in Python's search path. This happens to include the working directory.
There are many places to store one's modules, possibly the easiest is
/usr/local/lib/pythonx.y/site-packages
or
/usr/local/lib/pythonx.y/dist-packages
(whichever one is on your system).
Once in there you should create a directory for your stuff, create an empty __init__.py file in that directory, then copy your modules into it:
sudo mkdir MyStuff
sudo touch MyStuff/__init__.py
sudo cp /home/me/my_module1.py MyStuff/
sudo cp /home/me/my_module2.py MyStuff/
and then in your scripts you can
from MyStuff import my_module1
