def __is_or_has_file(self, data):
        '''
        Figure out if we have been given a file-like object as one of the inputs to the function that called this.
        Is a bit clunky because 'file' doesn't exist as a bare-word type check in Python 3 and built in file objects
        are not instances of io.<anything> in Python 2

        Returns:
            Boolean - True if we have a file-like object

        if (hasattr(data, 'file')):
            data = data.file
