I've been organizing my python projects starting with package folders.

Say I name my package "foo", foo is the top level folder for the source code. Inside foo there is a "main.py" file as the project's start point, and other various modules, let's have one called "module1.py". Now, add another package under "foo", the obvious example name here would be "bar", and add another module under "bar" called "module2.py".

The project structure looks like this:

  - foo/
    |- main.py
    |- module1.py
    |- bar/
       |- module2.py

To reference "module1.py" in "module2.py", just write

  import foo.module1

To reference "module2.py" in "main.py", do as follows

  import foo.bar.module2

There is no problem importing from any level.

To start the program from command line, enter:

python -m foo.main
