Chapter Summary
In this chapter, we explored concepts related to looping in Python. We took our first substantial look at the iteration protocol in Python—a way for nonsequence objects to take part in iteration loops—and at list comprehensions. As we saw, a list comprehension is an expression similar to a for loop that applies another expression to all the items in any iterable object. Along the way, we also saw other built-in iteration tools at work and studied recent iteration additions in Python 3.0.
This wraps up our tour of specific procedural statements and related tools. The next chapter closes out this part of the book by discussing documentation options for Python code; documentation is also part of the general syntax model, and it’s an important component of well-written programs. In the next chapter, we’ll also dig into a set of exercises for this part of the book before we turn our attention to larger structures such as functions. As usual, though, let’s first exercise what we’ve learned here with a quiz.
