If we wanted to add multiple key : value pairs to a dictionary at once, we can use the .update() method.

Looking at our sensors object from the first exercise:

sensors =  {"living room": 21, "kitchen": 23, "bedroom": 20}

If we wanted to add 3 new rooms, we could use:

sensors.update({"pantry": 22, "guest room": 25, "patio": 34})

which would add all three items to the sensors dictionary. Now, sensors looks like:

 {"living room": 21, "kitchen": 23, "bedroom": 20, "pantry": 22, "guest room": 25, "patio": 34}
