Adding a save message method to our Redis client

In redis.py, let's amend our imports to include uuid4:

from uuid import uuid4 

uuid4 generates us a unique random string that we can use for our message.

We can now add our new save_message method to the RedisClient:

    def save_message(self, message): 
        message_id = uuid4().hex 
        self.redis.set(message_id, message) 
 
        return message_id 

First off, we generate a new message ID using uuid4().hex. The hex attribute gives us the UUID as a 32-character hexadecimal string. We then use it as a key to save the message and return it.
