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 on 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 have taken a brief look at the itertools module, which is full of interesting iterators which can enrich our abilities with Python even more.

Now it's time to switch gears, to take another step forward and ...
