 Where the circuit python parsing today, I wanted to talk about using dictionaries inside of circuit Python. So a dictionary is a type of a data structure, sort of like a list, but the really neat thing about it is that we can ask for values associated with certain keys. So what you'll see in my code here, here I've actually named things for what they are. Dictionary is inside of these curly brackets, these different pairs of things like the text string blue, and then it has a related value, which is a color value here, these numbers and parentheses. What I'm doing in code here is, you can see down at the bottom, I'm using user input, and it says right here, please type the name of a key from your dictionary, and then it tells me the names of the different keys in my dictionary. So I'll type in green. It says, your entry matches a key in the dictionary, then it tells me what the value of that key is, in this case, the value of the green key is 0-255-0. Then I have it lighting up these neopixels here for a fun little effect, and then it moves forward and says, okay, try another one. If I type something that doesn't exist in here, let's do red, that's not in that list. It says, oh, red, that entry is not in the dictionary, sorry. So how this works, the key thing here, I'm calling the key whatever the user input is. So key equals input parentheses. So when I type something, the next thing that happens is I check if the key is in the dictionary. So that's a way to just look and see, does it match any of those entries for those first halves of those pairs? If it does, we print out a little statement, we take a pause, then we set the value variable to be equal to the dictionary at that key. So that's actually grabbing that value. I'm also calling it value just so it's really clear what it is right here. Then I print off a statement to let you know you've done the thing, filled the LEDs with that value. So in that case, when I typed in, let's do blue, it goes, it looks through the dictionary or any of the keys named blue, it finds one and then it sets that thing called value to be the value of the blue key inside of the dictionary. In this case is 00255 and then it lights up our LEDs. So it's a really nice way to work with a data structure, calling things by name and then getting their values returned to you. And so that's one way that you can work with dictionaries inside of CircuitPython and that is your CircuitPython Parsec.
