Package organization

[Mike Wyatt]

I've been playing around with Python for a few months now, and I just 
recently started looking at packages to organize my growing project.  So 
far, I've been organizing my application into one class per module.  
This has been working pretty well.  For example, I simply "import 
timer", then use "t = timer.Timer()" to allocate a new Timer object, .  
Unfortunately, this is yielding some pretty odd syntax when I use 
packages.  Here is a sample of my package structure:

/engine
    /graphics
    /input
    /world
    /timer
        timer.py       # contains Timer class
main.py

Let's say I want to create a Timer object in main.py.  I would need to 
do something like this:

import engine.timer.timer.Timer
t = engine.timer.timer.Timer()

Maybe I shouldn't have a module and package with the same name, but it 
seems the most logical design.  Unfortunately, the code is a bit ugly 
with "timer" included in the import three times.

Is there a better way to do this?  How do you guys organize your 
packages and modules?
