Christian Heimes added the comment: In fact it is a built-in method without a doc string:
>>> f = open("/dev/null") >>> f.close <built-in method close of _io.TextIOWrapper object at 0x7feefaab42f0> >>> f.close.__doc__ All functions and methods that are implemented in C are referred to as built-in functions. It's an implementation detail. ---------- nosy: +christian.heimes priority: normal -> low type: -> behavior versions: +Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18249> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
