try:
  print(caffeine_level["matcha"])
except:
  print("Unknown Caffeine Level")

5. Safely Get a Key

user_ids = {"teraCoder": 100019, "pythonGuy": 182921, "samTheJavaMaam": 123112, "lyleLoop": 102931, "keysmithKeith": 129384}

tc_id = user_ids.get("teraCoder", 100000)
print(tc_id)

stack_id = user_ids.get("superStackSmash", 100000)
print(stack_id)

6. Delete a Key

available_items = {"health potion": 10, "cake of the cure": 5, "green elixir": 20, "strength sandwich": 25, "stamina grains": 15, "power stew": 30}
health_points = 20

health_points += available_items.pop("stamina grains", 0)

health_points += available_items.pop("power stew", 0)

health_points += available_items.pop("mystic bread", 0)

print(available_items, health_points)

7. Get All Keys

user_ids = {"teraCoder": 100019, "pythonGuy": 182921, "samTheJavaMaam": 123112, "lyleLoop": 102931, "keysmithKeith": 129384}
num_exercises = {"functions": 10, "syntax": 13, "control flow": 15, "loops": 22, "lists": 19, "classes": 18, "dictionaries": 18}

users = user_ids.keys()

lessons = num_exercises.keys()

print(users, lessons)

8. Get All Values

num_exercises = {"functions": 10, "syntax": 13, "control flow": 15, "loops": 22, "lists": 19, "classes": 18, "dictionaries": 18}

total_exercises = 0

for i in num_exercises.values():
  total_exercises += i

print(total_exercises)

9. Get All Items

pct_women_in_occupation = {"CEO": 28, "Engineering Manager": 9, "Pharmacist": 58, "Physician": 40, "Lawyer": 37, "Aerospace Engineer": 9}

for x, y in pct_women_in_occupation.items():
  print('Women make up ' + str(y) + ' percent of ' + x + 's.')

spread = {}

spread["past"] = tarot.pop(13)

spread["present"] = tarot.pop(22)

spread["future"] = tarot.pop(10)

for x, y in spread.items():
  print('Your ' + x + ' is the ' + y + ' card.')
