New submission from Kaleb Barrett <dev.ktbarr...@gmail.com>:
The range builtin type is a collections.abc.Sequence, which in Python 3.5 added the optional start and stop arguments to the index method of Sequences. However, range.index does not support these optional arguments required by Sequence. I noticed this when creating a wrapper type around range which was a Sequence. mypy complained 'Signature of "index" incompatible with supertype "Sequence"', but attempting to pass the values raised 'TypeError: index() takes exactly one argument (3 given)'. ---------- components: Library (Lib) messages: 391029 nosy: ktbarrett priority: normal severity: normal status: open title: range.index doesn't support start/stop optional arguments type: behavior versions: Python 3.10, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43836> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
