You need to "reload" the module to pick up the changes.

>>> help(reload)
Help on built-in function reload in module __builtin__:

reload(...)
    reload(module) -> module

    Reload the module.  The module must have been successfully 
imported before.

In addition there is a Restart menu option in IDLE that will 
effectively
give you a new empty shell environment if you have lots of imported 
modules.

However I'm not sure if reload will work if you use the from X import 
*
approach since that imports all of the names rather than the module 
itself.
In that case restart is probably the best bet - or switch to the safer 
import X
style.

HTH,
