If you put a __main__.py file in the root directory of your project file, you can use the root directory to run the entire program.
Your project looks like this ex.
app/
|-test.py
|-test2.py
|-__main__.py
You can run the program like this
>> python app
The interpreter will execute the __main__.py file as the main program.
If you package the code into a zip file, the same will work.
ex.
>> cd app/
>> zip -r test.zip *.py
>> python test.zip
