is result.message in the code not string?

Question

i want to compare string published over pubnub and the other string so that i can accordingly put gpio pins high or low in raspberry pi3. if this "result.message" is not string then how do i convert this to string type. the message received by the python program over pubnub is stored in "message" which is object type. considering that the message published over pubnub is string type. the message printed on the terminal is perfectly fine but the comparing code is not working( if result.message is "stop":) here is python program
