I wrote the below code

    @functools.wraps(func)
    def wrap(self, *args, **kwargs):
        'Wrap    the    method    to    add    logging    function.'
        def _output_start_end_log(*_args, **_kwargs):
            'Output    the    log    of    the    start    and    the    end    of    the    method.'
            output_log(MSG.METHOD_START, method=func.__name__, config_group=self.configuration.config_group)
            ret = func(*_args, **_kwargs)
            output_log(MSG.METHOD_END, method=func.__name__, config_group=self.configuration.config_group)
            return ret
        return _output_start_end_log(self, *args, **kwargs)
    return wrap
