An idea worth considering: one can think of the “strip” family of methods as currently taking an iterable of strings as an argument (since a string is itself an sequence of strings): >>> "abcd".rstrip("dc") 'ab' It would not be a huge logical leap to allow them to take any iterable. Backward compatible, no new methods: >>> fname.rstrip(('.jpg', '.png', '.gif')) It even, in my opinion, can clarify "classic" strip/rstrip/lstrip usage: >>> "abcd".rstrip(("d", "c")) 'ab' Maybe I’m missing a breaking case though, or this isn’t as clear for others. Thoughts?
