Try/Except to Get a Key

We saw that we can avoid KeyErrors by checking if a key is in a dictionary first. Another method we could use is a try/except:

key_to_check = "Landmark 81" try: print(building_heights[key_to_check]) except KeyError: print("That key doesn't exist!")

When we try to access a key that doesn’t exist, the program will go into the except block and print "That key doesn't exist!".

Instructions

1.

Use a try block to try to print the caffeine level of "matcha". If there is a KeyError, print "Unknown Caffeine Level".

2.

Above the try block, add "matcha" to the dictionary with a value of 30.
