Category: Python Library Group: Python 2.3 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Frans van Nieuwenhoven (vannieuwenhoven) Assigned to: Nobody/Anonymous (nobody) Summary: tempfile files not types.FileType Initial Comment: a temporary file created with the tempfile module is not recognized as a types.FileType testcase: import types import tempfile # this will return False (I think it should return True) isinstance(tempfile.TemporaryFile(), types.FileType) ---------------------------------------------------------------------- >Comment By: Raymond Hettinger (rhettinger) Date: 2005-01-11 10:36 Message: Logged In: YES user_id=80475 Clarified the doc strings, noting that a file-like object is returned rather than an actual file. Instead of type checking the object, it is a better practice to use "duck typing" where you check for required methods (the interface) instead of an actual type or subtype. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1099516&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
