New submission from Antony Lee <anntzer.lee@gmail.com>: Unlike `PySequence_GetItem`, `PyTuple_GetItem` does not support negative indices ("indexing from the end"). That is fine, but warrants a notice in the docs (as that behavior is certainly not obvious). The same wording as for `PyList_GetItem` (changing "list" to "tuple") should be good enough (`PyList_GetItem` currently states: "The position must be non-negative; indexing from the end of the list is not supported. If index is out of bounds (<0 or >=len(list)), return NULL and set an IndexError exception.") ---------- assignee: docs@python components: C API, Documentation messages: 381716 nosy: Antony.Lee, docs@python priority: normal severity: normal status: open title: Indicate in the docs that PyTuple_GetItem does not support negative indices versions: Python 3.10 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue42451> _______________________________________
