That is not the correct URL to a discussion on this forum. The official
archives are at <URL:https://mail.python.org/pipermail/python-list/>, so
that's the correct place to look for a canonical URL to your message.

Great! This is modular programming, and is good practice.

You should make ‘common/’ a package directory, by creating
‘common/__init__.py’.

Once ‘common/’ is a package directory, you can::

    from ..common import my_functions

Put your modules into one or more packages.

Make sure each subdirectory of modules is a package.

Use explicit relative imports within your application.

Use absolute imports for shared libraries (ones shared between different
applications).
