Retrieving key-value data with Redis

Now that you've practiced storing key-value pairs with Redis and Python, it's time to explore the other half of that process: retrieving key-value pairs. In this example, you'll practice retrieving a few different key-value pairs that you might find in a web application built to report on weather data.

A connection object has been created and stored in the variable redis_conn. Enjoy!
