Correct: this change was made specifically so that objects could add their own format specifiers at a later time. If I recall correctly, This change was precipitated by wanting to add datetime.__format__: this change broke existing uses for format() that formatted datetimes as strings. But the result is that objects that really just want to be formatted as strings need to have their own __format__ which returns format(str(self), format_spec). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38222> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
