I believe this also comes down to a preference for EAFP over LBYL (http://mail.python.org/pipermail/python-list/2003-May/205182.html). i.e. instead of saying: if callable(foo): foo() else: # do something else you can instead say: try: foo() except TypeError: # do something else -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
