New submission from Claudiu Popa: For a couple of sequences (bytes, list, tuple, bytearray), the error when using an invalid sequence index is misleading, because it says that only integers are allowed, while slices are allowed too.
>>> a = [] >>> a['python'] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: list indices must be integers, not str >>> For instance, here's how range does it: >>> range(1)['a'] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: range indices must be integers or slices, not str The attached patch improves these error messages. ---------- files: proper_error.patch keywords: patch messages: 224029 nosy: Claudiu.Popa priority: normal severity: normal status: open title: Improve the error message for various sequences type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file36104/proper_error.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22077> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
