With all the discussion, I think you guys should realize that the find/index method are actually convenient function which do 2 things in one call: 1) If the key exists? 2) If the key exists, find it out. But whether you use find or index, at the end, you *have to* break it into 2 step at then end in order to make bug free code. Without find, you can do: if s in txt: i = txt.index(s) ... else: pass or: try: i = txt.index(s) ... except ValueError: pass With find: i = txt.index(s) if i >= 0: ... else: pass The code is about the same except with exception, the test of Exception is pushed far apart instead of immediately. No much coding was saved. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
