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

    def xsrf_required_decorator(self):
        expected_token = get_xsrf_token()
        actual_token = self.request.get('xsrf_token')
        if (actual_token != expected_token):
            self.response.set_status(403, 'Invalid    XSRF    token')
            self.response.out.write((('<h1>Invalid    XSRF    token</h1>\n' + '<p>Please    reload    the    form    page</n>\n') + ('    ' * 512)))
        else:
            method(self)
    return xsrf_required_decorator

What's a good function header?
