Expert Solution

Step 1

//Python Code:

# Create a dictionary of fruit and desserts made from the fruit. fruit is the key and the dessert is the value.
fruit_desserts = {'apple': 'sauce', 'peach': 'cobbler', 'carrot': 'cake', 'strawberry': 'sorbet', 'banana': 'cream pie'}

# Add the mango fruit to the dictionary. Its dessert is sticky rice.
fruit_desserts['mango'] = 'sticky rice'

# Change the strawberry dessert to shortcake.
fruit_desserts['strawberry'] = 'shortcake'

# remove carrot from the dictionary.
fruit_desserts.pop("carrot")

# Print the apple dessert.
print(f"apple dessert is: {fruit_desserts['apple']}")

# See if a banana dessert exists.
print(f"banana dessert exists: {'banana' in fruit_desserts}")

# See if a pear dessert exists.
print(f"pear dessert exists: {'pear' in fruit_desserts}")

# Print the keys in the dessert dictionary.
print(f"{fruit_desserts.keys()}")

# Print the values in the dessert dictionary.
print(f"{fruit_desserts.values()}")

# Print the key-value pairs in the dessert dictionary.
print(f"{fruit_desserts.items()}")
