Like Lists, Dictionaries are mutable. This means they can be changed after they are created. One advantage of this is that we can add new key/value pairs to the dictionary after it is created like so:
dict_name[new_key] = new_value
An empty pair of curly braces {}
is an empty dictionary, just like an empty pair of []
is an empty list.
The length len()
of a dictionary is the number of key-value pairs it has. Each pair counts only once, even if the value is a list. (That’s right: you can put lists inside dictionaries!)

Add at least three more key-value pairs to the menu
variable, with the dish name (as a "string"
) for the key and the price (a float or integer) as the value. Here’s an example:
menu['Spam'] = 2.50
