New submission from Rahul B <rahul.bish...@gmail.com>:
Even though item assignment throws error, the list inside tuple 'a' gets modified in place. Refer below, where the list value [8] gets added to the list value [5,6,7,7] at a[3] >>> a (2, 3, 4, [5, 6, 7, 7], 1) >>> id(a[3]) 140531212178376 >>> a[3]+=[8] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'tuple' object does not support item assignment >>> a (2, 3, 4, [5, 6, 7, 7, 8], 1) >>> id(a[3]) 140531212178376 ---------- messages: 366264 nosy: Rahul B priority: normal severity: normal status: open title: List item inside tuple seemingly allows for item assignment even after throwing error type: behavior versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40264> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
