New submission from bizywizy <bizy...@gmail.com>:
collections.UserString.format and collections.UserString.format_map return a string instaed of UserString. This is quite weird because I expect that the %-syntax and `format` method have to produce the same result. ``` >>> isinstance(UserString('Hello %s') % 'World', UserString) True >>> isinstance(UserString('Hello {}').format('World'), UserString) False ``` ---------- components: Library (Lib) messages: 360101 nosy: bizywizy priority: normal severity: normal status: open title: collections.UserString format and format_map return a string type: behavior versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39354> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
