Using Dictionaries

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!".

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

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