Unhandled exception warning

[Luke]

Having used Java for so long, I am used to being told during compilation 
that foo() throws an exception and that I need to catch it or throw it 
upward.  In Python you obviously don't get such reminders until it's too 
late.  Is there some script or IDE or something that can tell you that 
certain code may produce exceptions?  I'm sure this isn't an issue for 
those that know the modules inside and out, but when you're getting 
started it can be quite frustrating for your program to die suddenly and 
then be told, oh, by the way, spam() is capable of producing such and 
such exceptions.
