 For the CircuitPython parsec today, I wanted to show you how to use one-liners in CircuitPython. So what is a one-liner? Well, a one-liner is a series of commands that you've strung together using semicolons to separate them, which acts just like a line break in normal CircuitPython code. We can strain together a few little commands in order to test something, debug something, achieve an effect. Here you can see I've got a little text file, essentially, of some of these one-liners. Go to your REPL and then hit Ctrl-C to break the code. It'll stop the code from running, stop the current cycle of code. And now you essentially get this command prompt where you can talk to your board. So what I'm going to do is I'm just going to triple-click right here and copy import board, semicolon, dur, parentheses, board. If I come down into my REPL and paste that, automatically runs it. And now we get the list of pins that are available on this board. I'm going to grab this one. You can see this line here. It imports board, imports neopixel. Then it creates a neopixel object named LEDs. And then I'm going to fill it, in this case, fill it a purple color. So if I come down here into my command prompt and just hit paste, you can see it ran all of those separate commands, strings them together. And now I've changed the color of that neopixel. So this is a way that you can use one-liners inside of CircuitPython to speed up your debugging. And that is your CircuitPython Parsec.
