Counting Practice

If you're unsure whether a key exists in a dictionary, use the in keyword.

cars = {"ford": "f150", "toyota": "camry"}

print("ford" in cars)
# Prints: True

print("gmc" in cars)
# Prints: False

We need to report how many enemies are in our players immediate vicinity – but they want to know what those enemies are! Fix the count_enemies function. It accepts as input:

• enemy_names: a list of strings

It should return a dictionary where:

• The keys are all the enemy names from the list
• The values are the number of times each enemy appeared in the list

1. Run the code in its current state. It will raise a KeyError.
2. Fix the code: before updating a key's value, check if the key is already in the dictionary. If it is, increment it. If it isn't, set that key to 1 to create its first entry in the dictionary.
