I wrote the below code

    @functools.wraps(function)
    def wrapper(*args, **kwargs):
        session_kwargs = {'region_name': os.environ.get('AWS_DEFAULT_REGION', 'us-east-1')}
        profile_name = os.environ.get('PLACEBO_PROFILE', None)
        if profile_name:
            session_kwargs['profile_name'] = profile_name
        session = boto3.Session(**session_kwargs)
        self = args[0]
        prefix = ((self.__class__.__name__ + '.') + function.__name__)
        record_dir = os.path.join(PLACEBO_DIR, prefix)
        if (not os.path.exists(record_dir)):
            os.makedirs(record_dir)
        pill = placebo.attach(session, data_path=record_dir)
        if (os.environ.get('PLACEBO_MODE') == 'record'):
            pill.record()
        else:
            pill.playback()
        kwargs['session'] = session
        return function(*args, **kwargs)
    return wrapper

What's a good function header?

#Here is Python program to fix = ((self.
