3.6 Chapter summary

An object is a single unit of data in a Python program. So far, this book has introduced three types of objects: strings, integers, and floats. This chapter takes a closer look at how strings are represented and how integers and floats can be formatted. To better understand what an object actually is, the relationship between variables and objects is emphasized. The chapter also introduces two types of containers: lists and tuples. A container is an object that can hold an arbitrary number of other objects. At the end of this chapter, you will be able to solve more complex problems using fewer variables.
