Here's a good function header given the following:
I wrote the below code

    def _boto3_request(method):
        @wraps(method)
        def f(self, *args, **kwargs):
            rendered = method(self, *args, **kwargs)
            if (u'json' in self.headers.get(u'Content-Type', [])):
                self.response_headers.update({u'x-amzn-requestid': u'2690d7eb-ed86-11dd-9877-6fad448a8419', u'date': datetime.now(pytz.utc).strftime(u'%a,    %d    %b    %Y    %H:%M:%S    %Z'), u'content-type': u'application/x-amz-json-1.1'})
                resp = xml_to_json_response(self.aws_service_spec, operation, rendered)
                return (u'' if (resp is None) else json.dumps(resp))
            return rendered
        return f
    return _boto3_request

What's a good function header?
