All ways of assigning to __debug__ are forbidden: >>> __debug__ = 1 File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ >>> for __debug__ in []: pass ... File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ >>> with cm() as __debug__: pass ... File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ >>> class __debug__: pass ... File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ >>> def __debug__(): pass ... File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ >>> def foo(__debug__): pass ... File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ >>> import __debug__ File "<stdin>", line 1 SyntaxError: cannot assign to __debug__ The only exception is the assignment operator. >>> (__debug__ := 'spam') 'spam' >>> globals()['__debug__'] 'spam' This looks like a bug. ---------- components: Interpreter Core messages: 336100 nosy: emilyemorehouse, gvanrossum, serhiy.storchaka priority: normal severity: normal status: open title: Assignment operator allows to assign to __debug__ type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36052> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
