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}
