 What I wanted to show you today on the CircuitPython Parsec is how you can compare two different lists to each other. So this is really slick in CircuitPython. You can take one list and another list that are filled with values and simply ask, does this list have the same contents as this other list? You don't have to iterate through them or anything. You can just simply ask the question. And if those lists are the same, you can do something such as send a message, play a sound, unlock a lock. And in fact, the example that I'm using here is kind of like a combination lock or something you might find in an escape room. I have a couple of lists here. One is called Combo, like a combination lock. And you can see its current values are 4201. And then I have a second list that is called Dial. And the Dial is currently set at 0000. But I'm going to be updating the values in Dial as I change these knobs here and Dial in new numbers on my display. What you can see here is I have a little bit of code in my main loop that says, if the first list Dial is equal to the second list here, Combo, then we're going to go ahead and pause for a moment and then display the word open or do whatever other thing you want to do. So I'll do that right now. I'll go ahead and you can see each time I am changing a value here, it's going to run that check and see does this one list equal the other list. So 4201, boom, it says open. So that is really slick, really easy to do. All you have to do is say, does this list equal this other list? And CircuitPython takes care of all the rest. And so that is how you can do list comparison inside of CircuitPython. And that is your CircuitPython parsec.
