a short essay about programming
by kirby urner Dec. 8, 2022

Dec. 8, 2022

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

Searching for volunteers to user test PyPI.org
by Nicole Harris Aug. 16, 2019

Aug. 16, 2019

Hi folks, My name is Nicole - I work on PyPI.org, which is the principal repository for sharing Python packages. I am searching for new Pythonistas to help me user test some new security features on the website - specifically enabling/disabling two factor authentication. The point of these tests is to make sure that the new PyPI interfaces are easy to understand for people who are *not* experienced PyPI.org users. Things needed to participate: - An internet connection that is fast enough to be able to share screens - A smart phone on which we can install a TOTP application (most Androids or iPhones should work just fine) - 30 minutes to donate to the PyPI team Things *not* needed to participate: - Experience using PyPI.org (in fact, the less experience, the better) - An active PyPI account (we can set this up during the test) - Python experience If this is interesting to you, or members of your community, please sign up here: calendly.com/nlhkabu/pypi Thanks for your time! Nicole

school of tomorrow (another pilot)
by kirby urner July 24, 2019

July 24, 2019

Latest School of Tomorrow 5 min video, recapping some of what we've been doing in summer school in 2019. I've done similar pilots at Reed College. This time we're in Illinois. https://youtu.be/5_NWt_zjdcw (Codesters again) The kids (I have 15 on my roster) need to understand why a flight to China would go north, not west. In addition to learning Python. Actually, Python emulated in JavaScript. The Physics Engine is primitive, but having gravity, bouncy walls, speed variables on each sprite, collision detection, is a still a boon. Getting into physics this way makes sense to me.

Two new projects of potential interest
by Andre Roberge July 13, 2019

July 13, 2019

Hello everyone, For the past few weeks I have been working on two projects that may potentially be of interest to you. The first project is called friendly-traceback. I assume that, at one point or another, everyone on this list has taught beginners who were totally confused by Python tracebacks. Friendly-traceback aims to greatly reduce this confusion. As a bonus for international users, friendly-traceback has been designed from the start to be translatable; currently, only two languages are supported (English and French). There is much more to be done, but it is usable right now. You can find the documentation at https://aroberge.github.io/friendly-traceback-docs/docs/html/ Friendly-traceback has been carved out of a larger project named AvantPy. For English speakers, AvantPy can be thought of as standard Python + friendly-traceback + a few additional keywords that aim to reduce (slightly) the learning curve for some concepts. For non-English speakers, AvantPy makes it possible to run a "Python dialect" where Python's keywords are replaced by keywords written in a different language; currently there is a French and a Spanish version, both in draft forms. You can find the documentation at https://aroberge.github.io/avantpy/docs/html/index.html Both project are usable *right now*, even though they are admittedly incomplete. I would very much appreciate it if you could have a look at them, either just by reading the documentation or, even better, by trying to run the code, and give me some feedback. Of course, if you want to do more than simply give feedback and actually want to contribute some code samples or additional translations, that would certainly be welcome as well! :-) Pythonically yours, André Roberge

Calculator of Tomorrow (meme) on Medium
by kirby urner July 11, 2019

July 11, 2019

The Medium curators selected this one for widespread dissemination: https://medium.com/@kirbyurner/the-calculator-of-tomorrow-39ba87763621 It's on my usual theme: giving high schoolers a more significant experience by ditching scientific calculators in favor of "the calculator of tomorrow". I.e. instead of a "graphing calculator" we use pandas. The "of tomorrow" meme is retro futurism. Remember EPCOT? Now it's Epcot. Kirby
