I love using the random library - it's a simple way to introduce variety into simple programs and here's one example, what I call "Spock on a Chip." Here's a link to the repository.
Copy the files to a NeoTrinkey, changing "spock.py" to "code.py" - when it runs, it occasionally blinks lights, but when you touch one of the pads, it will blink and then pick a random quote out of the "spock" file and print it. If REPL=True, you'll need to be in an editor like mu to see the text. IF you change REPL to be False, then it will use HID support to send the text as if typed on a keyboard! Just the way to jazz up your email! Edit the "spock" file to add your own favorite quotes from everyone's favorite Vulcan.
What's going on?
There are two functions that are used to deliver the quotes. len_file(filename),
def file_len(filename): with open(filename) as f: for i, _ in enumerate(f): pass return i + 1
and wisdom(file_name).
def wisdom(filename):
qs = open(filename) for i in range(random.randrange(file_len(filename))+1): quote = qs.readline() quote = quote.rstrip() cmpthink() qs.close() return (quote.rstrip())
Give a file name, wisdom() calls len_file() to determine how big the file is, then uses random.randrange() to select the text - that means you can add or subtract from the "spock" file without needing to update the program.
The fun thing with this code is, it can be reused for other purposes. I've already used it to put together a "story" program that uses multiple source files (aliens, suns, planets, etc.) that can be drawn from to generate story lines. It could be used for a diceware style passphrase generator. And, of course, it doesn't have to be Spock on a chip - you can fill the "spock" file with any quotes you choose.
