Introduction

What you have learned

In an earlier module you learned how to index and slice strings.

Introducing lists

In this module, we will extend that knowledge to a new type of data called a list . This type of data, along with a string , is referred to as a sequence .

First, however, I will nail down some terminology from the Python Language Reference , The Python Tutorial -- 3.1.3. Lists , and The Python Standard Library -- 4.6. Sequence Types -- list, tuple, range .

A subscription

I referred to a subscription as an index in the earlier module titled Itse1359-1070-Strings Part 2 in this book .
