Creating Dictionaries

Add A Key

To add a single key : value pair to a dictionary, we can use the syntax:

my_dict["new_key"] = "new_value"

For example, if we had our menu object from the first exercise:

menu = {"oatmeal": 3, "avocado toast": 6, "carrot juice": 5, "blueberry muffin": 2}

and we wanted to add a new item, "cheesecake" for 8 dollars, we could use:

menu["cheesecake"] = 8

Now, menu looks like:

{"oatmeal": 3, "avocado toast": 6, "carrot juice": 5, "blueberry muffin": 2, "cheesecake": 8}

Create an empty dictionary called animals_in_zoo.

Walking around the zoo, you see 8 zebras. Add "zebras" to animals_in_zoo as a key with a value of 8.

The primate house was bananas! Add "monkeys" to animals_in_zoo as a key with a value of 12.

As you leave the zoo, you are saddened that you did not see any dinosaurs. Add "dinosaurs" to animals_in_zoo as a key with a value of 0.

Print animals_in_zoo.
