How should e.g. bytes.upper() be implemented then? The correct behavior is entirely dependent on the encoding. Python 2 just assumes ASCII, which at best will correctly upper-case some subset of the string and leave the rest unchanged, and at worst could corrupt the string entirely. There are some things that were dropped that should not have been, but my impression is that those are being worked on, for example % formatting in PEP 461. -- https://mail.python.org/mailman/listinfo/python-list
