A Dictionary is a way to store data just like a list, but instead of using only numbers to get the data, you can use almost anything. This lets you treat a dictionary like it’s a database for storing and organizing data any kind of data:
>>> stuff = {'name': 'Zed', 'age': 39, 'height': 6 * 12 + 2} >>> print stuff['name'] Zed >>> print stuff['age'] 39 >>> print stuff['height'] 74 >>> stuff['city'] = "San Francisco" >>> print stuff['city'] San Francisco
And that’s it. It is just really another kind of list, and a little bit simple once you get the hang of it
