Random Values and Non Repeating Randoms in CircuitPython 

In this lesson we explore the most useful functions in the Python random library, including randint, randrange, and choice. We'll use what we learn to randomly sparkle a CircuitPlayground using CircuitPython, and we'll then learn to use a while loop to prevent any values from being repeated. We'll end by showing how you can use the code you've just written to create a holiday ornament by adding just a few more low-cost parts.
