Maybe you should call the counter variable something meaningful instead of -- of all things -- "i", which is idiomatic for soething entirely else. And add a comment, and be done with it. > The solution that I had in mind is: > while True: > ... > if <condition>: break > if inifinte_loop(): raise infiinte_loop_exception This is a lot less understandable because whoever is working with your code will now have to check an additional function rather than a pretty self-explanatory variable increment. robert -- http://mail.python.org/mailman/listinfo/python-list
