Lessons > 12. While Loops

In this lesson, we’re going to go over while loops – a way of allowing your program to repeat code for a specified number of iterations. Being able to repeat code blocks (also know as “looping” or “iterating”) is very powerful, and will allow you to easily perform repetitive tasks in a variety of different contexts: playing songs, drawing pictures, building animations, doing data processing, and so forth. I also highly recommend that you read Chapter 5 in the Severance (Python for Everyone), for additional review.
