Chapter Summary
This chapter surveyed some more advanced module-related concepts. We studied data hiding techniques, enabling new language features with the __future__ module, the __name__ usage mode variable, transitive reloads, importing by name strings, and more. We also explored and summarized module design issues and looked at common mistakes related to modules to help you avoid them in your code.
The next chapter begins our look at Python’s object-oriented programming tool, the class. Much of what we’ve covered in the last few chapters will apply there, too—classes live in modules and are namespaces as well, but they add an extra component to attribute lookup called inheritance search. As this is the last chapter in this part of the book, however, before we dive into that topic, be sure to work through this part’s set of lab exercises. And before that, here is this chapter’s quiz to review the topics covered here.
