Dictionary
Dictionaries consist of key: value pairs.
Variables are stored in a dictionary with their names as keys, so dictionaries behave a lot like variables:
Dictionaries are not ordered.
Setting or getting the value of a key is simple and fast.
Dictionaries can't contain the same key more than once.
