To answer the part about how to run a python program on a PC:
First, you have to have Python installed on your machine. On Windows machines, you need to run it thus: C:> python myprog.py
Alternatively, you can write a batch file that takes your python program name as an argument and passes it to the call to the Python interpreter.
I use Linux myself, so all my python programs contain the first line: #! / bin/env python3
This allows me to simply invoke my program by name on the command line:
% myprog.py
