It’s time for our first look at a non-linear program. Up to now, all of our Python programs have executed step-by-step, start to finish, like a metronome, with each line of code getting executed exactly once. That’s about to change. In this chapter, we introduce the concept of a loop, which is a programming construct that directs lines of code to be executed repeatedly, and out of strict sequence.
