In the previous chapter, you learned how to write loops using detailed logic in order to help you help your program to make decisions. So far, though, you have not yet learned what to do with data. We have not created nor stored data. Yet, we know that video games store data! Video games sometimes store the names of players as well as the highest score that a player has achieved. How does one computer program remember all of this information? In this chapter, you will learn about some ways that Python can store and retrieve data, such as lists and dictionaries.

For the exercises and code in this chapter, your Python shell will be the best tool to use so that you can type your lists and dictionaries and then check the outcome of your coding. Otherwise, once your prompt is available, you can type lists and dictionaries, your shell will remember the information that you enter, and then you can test how to retrieve, add, and remove information...
