It could even be introduced without breaking compatibility. if being defined as str.rstrip([iterable]) so you could either call string.rstrip( [ '-dir' ] ) or as string.rstrip( '-dir' ) However I wouldn't be sure, that it really reduces the amount of questions being asked. In order to reduce the ambiguities one had to have two distinct functions. If one wouldn't want to break backwards-compatibility, then the new names would be for stripping off prefixes / suffixes and could be str.strip_prefix(prefixes) / str.rstrip_suffix(suffixes) I'd love to have this functionality, though I can live with importing my self written function. -- http://mail.python.org/mailman/listinfo/python-list
