Happy to make a PR! In my mind I had been thinking it would be the get_identifiers() method with the implementation above, returning a list. As for __iter__, I'm less clear on what that would look like: t = string.Template(...) for identifier in t: # what would I do here? # would it include repeats if they appear more than once in the template? I guess there are two ways to think about it: one is "what identifiers are in this template?" which I think should return a list with no repeats, which I can then iterate over or check if a value is in it. The other is, "what are the contents of the template?" in the style of string.Formatter.parse(). Given that string.Template is supposed to be the "simple, no-frills" thing in comparison to string.Formatter, I see less use for the latter option. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46307> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
