There are at least 3 reasons 1. pointer comparaition optimization quite common usecase in CPython codebase. e.x) list.count 2. if you create the range object, step = 1 which is singleton object is quite high percentage use case. - range(100) -> step = 1 - range(-100, 100) -> step =1 - range(-100, 100, 2) -> step != 1 3. fast path code does not cost high difficulty maintainence for this case but can bring 12% performance enhancement. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41902> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
