Get response from dictionary in chatbot

Question

I'm creating a simple chatbot working with random.choice() of possible responses to possible comments.

I would like to know how to work with dictionaries instead of return. And whether this ould be more advantageous for my code:

def create_response(self, menss, first_message):
    if first_message == menssin ('ok'):
        return random.choice(['Ok'])
    if menss == menss in ('hi'.lower(), 'hello'.lower(), 
        return random.choice(['Hi', 'Hello', 'Helloo'])
    elif menss  == menss in ('Y?'.lower(), 'Wbu?'.lower()):
        return random.choice(['No.', 'Nop.'])

Answer 1

How about this:

def __init__(self): 
    self.inventory = [
        (['Format:', 'List', 'of', 'questions'], ['list', 'of', 'possible', 'answers']),
        (['ok'], ['Ok']),
        (['hi', 'hello'], ['Hi', 'Hello', 'Helloo']),
        (['y?', 'wbu?'], ['No.', 'Nop.']),
    ]


def create_response(self, user_message):
    for questions, answers in self.inventory:
        if user_message.lower() in questions:
            return random.choice(answers)

This returns None when the user_message was not found in any of the questions.
