Creating a Dictionary
A dictionary is a data structure that stores unordered key-value pairs.
Imagine you need to create a dictionary called student with these pairs:
| Key | Value |
'first name' | 'Ann' |
'last name' | 'Elliot' |
'city' | 'New York' |
Check out the code to make this dictionary.
In a dictionary, you can use any immutable data type for a key. For instance, the dictionary we just looked at has strings as keys. Now, let's whip up a dictionary using numbers as keys.
Remember, the value associated with a specific key can be anything — strings, numbers, lists, and so on.
It's time to practice!
