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

    class FakeSocket(object, ):
        def __init__(self, *args, **kwargs):
            pass
        def fileno(self):
            return 42
    class FakeSendFile(object, ):
        def __init__(self, req):
            self.req = req
        def sendfile(self, o, i, offset, nbytes):
            os.lseek(i, offset, os.SEEK_SET)
            prev_len = len(self.req.body)
            self.req.body += os.read(i, nbytes)
            return (len(self.req.body) - prev_len)
    class FakeGlanceConnection(object, ):
        def __init__(self, *args, **kwargs):
            self.sock = FakeSocket()
            self.stub_force_sendfile = kwargs.get('stub_force_sendfile', SENDFILE_SUPPORTED)
        def connect(self):
            return True
        def close(self):
            return True
        def _clean_url(self, url):
            return (url.replace('/v1', '', 1) if url.startswith('/v1') else url)
        def putrequest(self, method, url):
            self.req = webob.Request.blank(self._clean_url(url))
            if self.stub_force_sendfile:
                fake_sendfile = FakeSendFile(self.req)
                stubs.Set(sendfile, 'sendfile', fake_sendfile.sendfile)
            self.req.method = method
        def putheader(self, key, value):
            self.req.headers[key] = value
        def endheaders(self):
            hl = [i.lower() for i in self.req.headers.keys()]
            assert (not (('content-length' in hl) and ('transfer-encoding' in hl))), 'Content-Length    and    Transfer-Encoding    are    mutually    exclusive'
        def send(self, data):
            self.req.body += data.split('\r\n')[1]
        def request(self, method, url, body=None, headers=None):
            self.req = webob.Request.blank(self._clean_url(url))
            self.req.method = method
            if headers:
                self.req.headers = headers
            if body:
                self.req.body = body
        def getresponse(self):
            mapper = routes.Mapper()
            api =...

What's a good function header?
