New submission from Donald Hobson <donaldphob...@yahoo.co.uk>:
Almost all of python makes the abstraction that ints are a single type of thing, the fact that some ints are too big to store in 8 bytes of memory is abstracted away. This abstraction fails when you try to reverse large ranges. >>> reversed(range(1<<63)) <longrange_iterator object at 0x7f0925d26660> >>> reversed(range(1<<63-1)) <range_iterator object at 0x7f0925d26600> >>> type(reversed(range(1<<63-1))) <class 'range_iterator'> >>> type(reversed(range(1<<63))) <class 'longrange_iterator'> >>> type(reversed(range(1<<63-2)))==type(reversed(range(1<<63-1))) True >>> type(reversed(range(1<<63-1)))==type(reversed(range(1<<63))) False ---------- components: Interpreter Core messages: 340614 nosy: Donald Hobson priority: normal severity: normal status: open title: Minor inconsistancy with types. type: behavior versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36693> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
