When would you know in advance you want 2 parts? Compare file.tar.gz to backup.2010.04.20.tar. I'd think the usual case would be
split if gz or zip or...: split again
Right, that's from the user point of view, and that's why I was thinking about numext in the first place, to be able to do what you describe (a loop with a split position that moves) my undertsanding now is that we would need to iterate from the longest-match to the shortest-match, until we find a pattern that works, so numext should be done from the left to the right. Or maybe simply drop that idea and just use path.endswith(extension)... :) In that case the only subtle case is when the filename starts with '.', So what about a new API : os.path.hasext(path, extensions) That would return True if the path match on extension provided in the extensions sequence (using .endswith, but ignoring the first dot if the filename starts with a dot) Tarek -- Tarek Ziadé | http://ziade.org
