Now I'm making a little desktop app using wxpython, and I want to use (import) that module. Using PyCharm, I have two separate projects in sibling directories. And there's another separate command line tool that wants to do the same. Currently, I just place a symlink to the, local to the directory of these apps. This seems like "the quickest thing that could possibly work", but I'm assuming there's a more pythonic way to approach this general problem.

import sys
print sys.path

This will show you your path for imports. The actual directories change
by default with different python versions, but one of them will be
suitable for putting new modules to be imported. Naturally, you don't
want to add to the place where the stdlib is placed, but some of those
are normal writable directories. There are also several ways to add your
own directories to that path, but maybe you don't need that complexity yet.

I'm sure others will be able to be more specific.
