Exercise 40: Dictionaries, Oh Lovely Dictionaries

Now I have to hurt you with another container you can use, because once you learn this container a massive world of ultra-cool will be yours. It is the most useful container ever: the dictionary.

Python calls them "dicts", other languages call them, "hashes". I tend to use both names, but it doesn't matter. What does matter is what they do when compared to lists. You see, a list lets you do this:

>>> things = ['a', 'b', 'c', 'd']

>>> print things[1]

b

>>> things[1] = 'z'

>>> print things[1]

z

>>> print things

['a', 'z', 'c', 'd']
