Is it possible to have a separate lib and src directory in Python?

Question

I'm writing a program with a client and a server and I'm trying to organise my source files in an intuative way. I've got this rough file structure:

src:  
    client:  
        client.py  
    server:  
        server.py

lib:
    clientlib:
        client_depend.py
    serverlib:
        server_depend.py
    commonlib:
        both_depend.py

Previously, I was using the methods which described in this SO Post but the number of sys.path.append("../..")s has gotten out of hand and is in danger of breaking if I move any files about.

What would be a neat and pythonic way to do this? I've thought about making lib a package and putting it in $(PYTHONDIR)/Lib/site-packages but that adds complexity to development (as it's a root owned dir and it's not on my USB drive that I use for development so I can change computers easily).

Thanks in advance.

Why not making modules that you could import easily when and where you want?

Like this:

src:
    __init__.py
    client:
        __init__.py
        client.py
    server:
        __init__.py
        server.py

lib:
    __init__.py
    clientlib:
        __init__.py
        client_depend.py
    serverlib:
        __init__.py
        server_depend.py
    commonlib:
        __init__.py
        both_depend.py

Then in client.py, you would just have to do:

from lib.commonlib import both_depend
from lib.clientlib import client_depend
