A concrete example would really help if you hope to persuade anyone that your way is better.
I find that Python's ability to extract the control part of a loop into a generator is an extremely powerful way to make loops much clearer for several reasons: you separate completely the 'what we are looping over', and 'when do we stop' from the 'what do we then do with each item'; also you have an opportunity to give the code controlling the loop a separate (and meaningful) name. -- http://mail.python.org/mailman/listinfo/python-list
