Sets, Tuples, and Dictionaries

Here is more practice with tuples and dictionaries. In addition, the Python built-in data structure known as a set is also covered. Sets are not ordered, and their elements cannot be indexed (sets are not lists). To understand Python set operations, remind yourself of basic operations such as the union and intersection. Use this tutorial to compare and contrast the syntax and programming uses for lists, tuples, sets, and dictionaries.

Introduction

Now that we've got the basics of strings and numbers and lists down, let's talk about the advanced data types - tuple, dict and set. These are container objects that let us organize other types of objects into one data structure.
