Python. AttributeError: 'str' object has no attribute for the words

Question

GREETING_KEYWORDS = ("hello", "hi", "greetings", "sup", "whats up",)
GREETING_RESPONSES = ["sup bro", "hey", "*nods*", "hey you get my snap?"]
def check_for_greeting(sentence):
    for word in sentence.words:
        if word.lower() in GREETING_KEYWORDS:
             return random.choice(GREETING_RESPONSES)
user= input(">>> ")
check_for_greeting(user)

AttributeError: 'str' object has no attribute 'words'. sentence.words is not proper. How to get the GREETING_RESPONSES if user is giving input in GREETING_KEYWORDS. I am using python 3.5

You have to tell Python about that intention. Use the split() method to do that:

def check_for_greeting(sentence):
    words = sentence.split()
    for word in words:
        if word.lower() in GREETING_KEYWORDS:
