Summary

In this chapter, we've taken another step toward expanding our coding vocabulary. We've seen how to drive the execution of the code by evaluating conditions, and we've seen how to loop and iterate over sequences and collections of objects. This gives us the power to control what happens when our code is run, which means we are getting an idea of how to shape it so that it does what we want and it reacts to data that changes dynamically.

We've also seen how to combine everything together in a couple of simple examples, and in the end, we took a brief look at the itertools module, which is full of interesting iterators that can enrich our abilities with Python even more.

Now it's time to switch gears, take another step forward, and talk about functions. The next chapter is all about them because they are extremely important. Make sure you're comfortable with what has been covered up to now. I want to provide you with interesting examples, so I'll have to go a little faster. Ready? Turn...
