Actually things are more complex. TemporaryFile is not a class, it is a function, so it does not make sense to use it with isinstance(). And if add support for TemporaryFile, NamedTemporaryFile and SpooledTemporaryFile should be supported too. It may be easier to use a virtual subclassing: register IOBasePayload with a class which has an __instancecheck__() method which checks the existence of attributes "read" and "close". ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33762> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
