Depends on the size of the classes... I tend to write as small as
possible classes, so I usually have a bunch of closely related classes
(and functions and constants...) in a module.

Sorry, but I don't see the correlation between compilation and import
As for imports, you have to import each needed symbol anyway - from
module import * is really bad practice IMHO, except in the shell, and
then it's just a matter of packaging related modules together (which
should be the case anyway) and setting the __all__ attribute of the

cf above. And/or browse the standard lib's sources - you know, it's Open
python -c "print '@'.join(['.'.join([w[::-1] for w in p.split('.')]) for
p in 'onurb at xiludom.gro'.split('@')])"
