some day ago there was a discussion right about that....

however a simple solution is to raise an exception and catch it outside the 
loop.

class Stop(Exception): pass

try:
    	for ...
    	    	for ...:
    	    	    	if  ...: raise Stop
except Stop:

you could also throw some existing Exception, but when you use you own 
youre sure that you don't accidently drain an error.
