If you do for word in sentiment, sentence is a string, so for each character of the string you entered is repeated. It's no wonder the result is None.

What you want to do is to repeat Greeting_Keywords and check if sentence.lower() contains the greeting keyword. I made a demo so please run it and check it out.
