a short essay about programming
by kirby urner 08 Dec '22

08 Dec '22

A common "error" (not too serious) that I see in beginning Python (and no doubt other languages, but Python is the one I'm teaching), is having a while condition that appears to put a lid on things, but then the flow all leaks away through break statements, such that the "front door" condition is never revisited. while guess != secret: guess = int(input("Guess?: ") if guess == secret: print("You guessed it!") break else: print("Nope, try again...") What's messed up about the above code is you never really go back to the top in the case where you'd get to leave. Rather, you exit by the back door, through break. So in that case, wouldn't have been simpler and more elegant, even more "correct" (dare I say it) to have gone: while True: # no ifs ands or buts guess = int(input("Guess?: ") if guess == secret: print("You guessed it!") break else: print("Nope, try again...") I see lots of heads nodding, and that could be the end of the matter, but then a next question arises: wouldn't this also be a more correct solution?: while guess != secret: guess = int(input("Guess?: ") if guess == secret: print("You guessed it!") continue # instead of break else: print("Nope, try again...") We're back to having a variable while condition, not a boolean constant, but this time we actually exit by means of it, thanks to continue or... while guess != secret: guess = int(input("Guess?: ") if guess == secret: print("You guessed it!") else: print("Nope, try again...") ... thanks to no continue. This last one is getting a thumbs up, but then I'd pause here and say "continue" can be easier on the eyes. It's unambiguous where it takes you, in contrast to having to scan on down the gauntlet, looking for possibly other open doors. "What happens next" should not require scanning ahead too far. Help us not to get lost. Be a civic-minded coder. I'm thinking of a programming style that advises two things: (a) if you use a while condition that's variable, that's expected to change, then your goal should be to always exit because of that, i.e. that should be your only exit point. Even if some other criterion suggests exiting, you have the option to flip that "lid" at the top, to crack that front door, and bounce the ball out. (b) which is why 'continue' is your friend. You are showing the user where your 'break' statements are, except you don't use "break" statements, as you've given a non-constant condition, and your aim is to make that your ONLY exit point. In short: never use break to exit a while loop unless your condition is while True. Instead, always flip the condition and exit through the font door. However, as soon as I make that rule I can think of good reasons to break it. The other programmers in the room are shaking their heads. Won't we lose information, needed elsewhere in the program, if we "artificially" force a True condition to False. Aren't we, in effect, lying? That concern could be addressed. Keep all the info true, just treat the "lid condition" (it "keeps a lid on it") as a flag. Go ahead and remember the user's guess. allowed = 5 tries = 1 exit = False while not exit: # no other way out guess = int(input("Guess?: ") if guess == secret: print("You guessed it!") exit = True # instead of break continue print("Nope, try again...") tries += 1 if tries == allowed: print("You've maxed out") exit = True continue I think we all understand the main issue: writing reader-friendly code, and rules for doing so. There's something comforting about approaching a while loop and knowing its not a leaky sieve, riddled with back doors, maybe even an exit( ) time bomb. But in the recursion world we want a minimum of two exits usually: when another round is called for versus when we've "hit bottom". Can we have it both ways? Conclusions: Lets not be too hasty with rules of thumb and: Lets keep the reader in mind when writing code. Just because the interpreter knows to compute the flow unambiguously, doesn't mean all ways of writing it are equally reader-friendly. What may seem a gratuitous gesture, an unnecessary flourish, may actually promote reader comprehension of your code, and that should be a goal as much as satisfying the interpreter. Kirby

What countries have Python in official high school curriculum?
by Jurgis Pralgauskis 04 Jan '22

04 Jan '22

Hi again :) we want to promote Python in my small country (Lithuania), In high-schools we officially have Pascal (for 30years) and C++ (for 10years) now -- as it is accepted in final IT/programming exam (and olymiads). I know that it is not common to have programming exam, but still if you know some (esp, big) countries commonly using it while teaching - please let know :) Thanks -- Jurgis Pralgauskis tel: 8-616 77613; Don't worry, be happy and make things better ;) https://galvosukykla.wordpress.com/

update on Pythonic High School curriculum writing
by kirby urner 20 Aug '21

20 Aug '21

Here's an updated link to my open source curriculum writing. https://nbviewer.jupyter.org/github/4dsolutions/elite_school/blob/master/Ho… Pythonic High School Math one might call it, with bridges to other STEAM topics, and thence to PATH. [1] I introduce folks to my Notebooks using nbviewer because the native Github rendering is less thorough i.e. LaTeX is not interpreted. LaTeX, Git, SQL... all important high school topics. Kirby [1] I'm not sure how much PATH caught on after Andrew Hacker used it in The Math Myth. An attempt to map the Humanities with four letters, copying the STEM idea (Science Technology Engineering Mathematics for those of you not using this namespace). I've customized PATH to mean Philosophy Anthropology Theater History, with Theater having an expanded meaning ("all the world is a stage"). Then the local custom is to expand STEM to STEAM saying A is for Art and claiming here's a way to bridge the CP Snow Chasm twixt the Sciences and the Humanities. My wrinkle is to use A for Anthropology (which includes Art in my account) and to intersect on this Science-Humanities topic (the study of we humans and our many subcultures i.e. cults).
