My answer is to put read-only files right with the py* files, and
writable files in the user's space. In the former case, you can find
the files by parsing __file__ for one of your modules. In the latter
case, it's system dependent.
For those read-only resources I'd use pkgutil.get_data (instead of
manually parsing __file__):
http://docs.python.org/library/pkgutil.html#pkgutil.get_data
It's easier to manage when someone later decide to install the package as
an egg file, or distribute it using py2exe. Quoting the documentation:
"""The function returns a binary string that is the contents of the
specified resource.
For packages located in the filesystem, which have already been imported,
this is the rough equivalent of:
d = os.path.dirname(sys.modules[package].__file__)
data = open(os.path.join(d, resource), 'rb').read()
return data
