New submission from Alexander Mohr <thehes...@gmail.com>: Currently subscriting a attribute that's None reports the following: >>> class Foo: pass >>> Foo.organizer = None >>> Foo.organizer['start'] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'NoneType' object is not subscriptable
What would be nice is if it were to report the name of the attribute that is not subscriptable as it would greatly help in the logs, something like: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'NoneType' object of attribute 'organizer' is not subscriptable just a thought. Otherwise one would need to sprinkle their code with asserts, especially if it's a compound statement like: Foo.organizer.blah[0], you wouldn't know which attribute wasn't None ---------- components: Interpreter Core messages: 309187 nosy: thehesiod priority: normal severity: normal status: open title: subscriptable type: enhancement versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32448> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
