Lets say I have projects x and y in brother directories: projects/x and projects/y.
There are some utility funcs common to both projects in myutils.py and some db stuff in mydbstuff.py, etc.
Those are minor common goodies, so I don't want to create a single package for them.  
Questions arise about the whereabouts of such files, possible changes to PYTHONPATH, proper way to import, etc.  
What is the 'pythonic way' to use such files?
I agree with 'create a package'.
If you cannot do that, how about using symbolic links/junctions (ln -s on Linux, linkd on Windows)?
What is the pythonic way to share common files in multiple projects?
