Mark Dickinson added the comment: Surprisingly, this is valid syntax. Your first line is parsed as:
0xf or (python is weird in ways) Because `or` is short-circuiting, its right-hand operand (which is also valid syntactically, being a chained comparison) is never evaluated, so we don't see the `NameErrors` that you might expect. >>> python is weird in ways Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'python' is not defined Your second example is similar. Closing as 'not a bug'. ---------- nosy: +mark.dickinson resolution: -> not a bug status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21979> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
