 For today's circuit Python Parsec, I wanted to show you how you can use the enumerate command in order to get a list of items and their index numbers or indices. So here you can see in the code I have importing time and OS, and that's because I'm going to grab a list of files that are on this Feather RP2040 right here. I'm going to call that list the song files list, and then I'm going to go ahead and use this command right here for index comma file in enumerate song files. That is going to create two variables. One is going to be the index and one is going to be the name. And those come from this enumerate command, which is going to enumerate through that whole list, whatever that song file list was. In this case, what I do with them is I print them out, and then later what I do is I ask for user input on one of those index numbers, and then I'll print that number. This is just a placeholder for actually playing a file. So here you can see I've started up the Feather, and I'm going to go ahead and restart it. What you'll see is it says, okay, song's available, and it goes through and it gives me this enumeration of an index, zero, clay guys, Bartlebeats, MP3, one, small selective Bartlebeats, two, Daisy Bartlebeats, and then it says pick a song. So I'll say how about two, press enter, and then we can pretend that goes and plays the song there. So this is a really nice way to work through lists, especially really large lists if you want to, and get yourself in a really simple piece of code, the index and the value right out of your list. So that is one way you can enumerate in CircuitPython, and that is your CircuitPython parsec.
