New submission from Kevin Orr: When one uses a file object returned by `FileType.__call__` as a context manager, `sys.stdin`'s or `sys.stdout`'s `__exit__` will be triggered upon exit of the context, in turn calling their `close` method.
Perhaps the issue is that `sys.stdin` and `sys.stdout` have poor `__exit__` methods, but my proposal (and it's not a particularly clean one) is to override the file object's `__exit__` if it happens to be either `sys.stdin` or `sys.stdout` to simply return True when called. ---------- components: Library (Lib) messages: 231249 nosy: keviv priority: normal severity: normal status: open title: argparse.FileType.__call__ returns unwrapped sys.stdin and stdout type: behavior versions: Python 2.7, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22884> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
