You could try putting all the imports into a single module 
and them importing that module. The new imported module 
should be compiled into Python byte code the first time 
you import it which might be faster on subsequent runs 
- I've never tried this so I'm interested in the results!

If you split your code into modules and import them at
the Python prompt you can sometimes develop code 
in one module while avoiding imports of the rest, but 
its not 100% effective.

There are lots of ways around this, including
FastCGI, mod_python, one of the many Python 
web frameworks. Look at this page for lots of 
options:
