| 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) | ||

| 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. |
