Chapter 8. Lists and Dictionaries

This chapter presents the list and dictionary object types, both of which are collections of other objects. These two types are the main workhorses in almost all Python scripts. As you’ll see, both types are remarkably flexible: they can be changed in-place, can grow and shrink on demand, and may contain and be nested in any other kind of object. By leveraging these types, you can build up and process arbitrarily rich information structures in your scripts.
