I get:
>>> import Lib
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: No module named Lib

I guess there's a Lib/__init__.py.

But onto the point you're making. I think its possibly a mis-viewing
of the package idea in Python. A package creates a name space. If you
create Lib/Server/Db with all the __init__.py files, its because you
want to import Lib.Server.Db,  rather than a way of organising your
source files.

If you want to have a single name space, and keep the nested
arrangement of directories, you can add python code in Lib/__init__.py
to traverse directories and import packages that you find. Or you can
define any rules for mapping files and directories to the name space
you desire.
