Python has a wide variety of built-in collections. In Chapter 4, Built-In Data Structures Part 1: Lists and Sets, we looked at them closely. In the Choosing a data structure recipe, we provided a kind of decision tree to help locate the appropriate data structure from the available choices.

When we consider built-ins and other data structures in the standard library, we have more choices, and more decisions to make. How can we choose the right data structure for our problem?
