Chapter 6. Lists and Dictionaries

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