There is an issue with the program when the user correctly guesses the number. The program should end when the break statement executes in the while loop found in main(), but instead it times out.
import random
def main():
level = get_level()
number = generate_random_number(level)
while True:
guess = get_guess()
if check_guess(number, guess) == False:
continue
else:
break
def get_level():
while True:
level = input("Level: ")
try:
int(level)
except ValueError:
continue
if int(level) <= 0:
continue
else:
return int(level)
def generate_random_number(level):
number = random.randint(1, level)
return number
def get_guess():
while True:
guess = input("Guess: ")
try:
int(guess)
except ValueError:
continue
if int(guess) <= 0:
continue
else:
return int(guess)
def check_guess(number, guess):
if guess > number:
print("Too large!")
return False
if guess < number:
print("Too small!")
return False
if guess == number:
print("Just right!")
return True
main()
Maybe try using the idiom:
if __name__=="__main__": main()Instead of calling main since the way it’s written now it will always run your code as soon as your module is imported. If the system expects a function named main and calls it, remove your call to main at the end.
My name’s not Shirley nor May. Meaning, the process guard has a name and it’s not idiom.
That passed the test! Thank you!
Nothing really sticks out. It could also be something about how the automated checker provides input (maybe it expects to not press enter or something and it’s stuck at input()… hard to say)
I personally would install ruff and run “ruff check yourfile.py” and then later “ruff check --select=ALL yourfile.py” and read about everything it complains about.
Google the error codes and find the description and discussion of each and why it is complaining, sometimes they’re not a big deal, sometimes they are aha moments. Ruff has a page discussing each warning and error
Actually I think it may be your get_entry() code. The try traps all non-numbers and restarts the loop for new entry. So like typing “exit” or an empty string or anything that’s not convertible to a number is being trapped by the raise and sent back for reentry. And anything that is a number can’t hit the break. Just my guess.
I second this! Add a print(“invalid number, try again”) or something to verify and avoid silent failures.
What happens if you replace the last break in main() with exit()?
The code looks like it should run fine. How are you executing it and what makes you think it “times out”?
It’s for CS50P which uses a customized VS Code. It has an automated code checker which I ran when I was done.
outputs “Just right!” when guess is correct
timed out while waiting for program to exit
How is that checker configured?
It might be doing something like this:
import student_module student_module.main()and because you’re already invoking
mainas the module is imported, it’s getting stuck the second time around. Maybe add some indicativeprintat the entrypoint to your main function.Another reply in here has supplied the standard idiom for making a module executable:
if __name__ == "__main__": main()What duh eh does
standard idiommean?In computer programming, a programming idiom, code idiom or simply idiom is a code fragment having a semantic role[1] which recurs frequently across software projects. It often expresses a special feature of a recurring construct in one or more programming languages, frameworks or libraries. This definition is rooted in the linguistic definition of “idiom”.
https://en.wikipedia.org/wiki/Programming_idiom
So this term is vague and abstract. Really not a specific term or grouping of related things.
The actual terminology
That standard idiom is called, process guard or simply guard. Learn about this term when doing anything involving multiprocessing.
The if __name__ == “__main__”: guard is important when working with multiprocessing in Python. This prevents the creation of duplicate processes when the module is imported.
https://labex.io/tutorials/python-how-to-pass-arguments-in-python-multiprocessing-430780
So it’s totally not for what its being described as. Or that’s an oversimplification with a loss of vital details of it’s actual purpose.
It could be worse
When don’t know the name for something, Call it stuff!. Ya know, when really suack at naming things, be unrepentant! Stuff is as bad of a term i could come up with. Means didn’t know how to describe it to accurately relate what it is or does, without being vulgar; out of fear the typos author left an Easter egg which is best left lie.
Used this term once, for a SQLAlchemy non-request based router implementation, the Session (term already taken) i call SessionStuff. Doesn’t that just scream competence and authoritative implementation?
What do you do for a job? Urrrh … stuff?
Regretted immediately and still do. Cuz session seems to have three different contexts / meanings.
Oh shit! Used the term, stuff. That’s code prefer to not even read. That’s a thing of nightmares that haunts our collective waking moments.
You sound angry. Take a breath and grow up.
The idiom allowed it to pass the checker’s tests! Thanks for your help!
You picked up an STD from mvirts. That dodgy terminology has been passed on and added to your lexicon.
South Park suggested the cure for this, eat a banana. Life doesn’t have to make sense, roll with it.
Quickly taking a shower was oddly never suggested.
Do you know how to use breakpoints? Put one on “Just right!” and then step through it.
Edit: I just ran the code and it exits properly. It’s probably your customized VS Code . Which command is it using to run your code?
try running the code outside the special editor, just
python3 whatever_file_the_code_is_in.py. if it works as it should, then something is wrong with the environment you have been provided.It seems to run fine. You should likely as a TA or something as this appears to be something specific to your environment.
probably indentation issue, make sure to have 4 spaces on each indent level
1 2 3 4
1 2 3 4
1 2 3 4 5
1 2 3 4 1 2 3 4 1 2 3
Opps!
Was using tabs but I went through it to make sure and seemed to be ok.
Don’t think that’s a literal suggestion.
More like a subtle way to portray his frustrations having to look through code example with three while(True) loops?
If you set up ruff you should get autoformatting (and you can enable various lints).
or not introducing another programming language into your toolchain by sticking with black, flake8, isort, and pre-commit
At the user level they’re just tools, not programming languages. Python users are generally moving to
ruff(anduv) because of ergonomics: It works well and really fast which makes for a smooth experience in-editor. Plus using fewer tools to achieve a similar result is generally desirable.And for a complete newbie like someone taking a course, I think there’s no “sticking with” to speak of. Might as well just skip over the tools people are migrating away from and start with the tool people are migrating to.

Cannot see the issue at first glance, but you can try to write “return null” instead of break. That should always exit the function.
Having multiple return statements in one function is a mistake. There shall ever be only one, unless that’s unworkable due to tons of checks.
Cringe! That’s like watching bad movies for the joy of really really bad movie moments. Watch
Dead Snow IITHENDead Snow I. Both are cringe. Former good cringe later really really bad cringe. Do not watch in chronological order.A return statement within a while loop. Is that good or bad cringe?
Code with multiple return in one function/method screams noob. Especially when its completely unnecessary and avoidable. The return statement in random locations is a close 2nd.
The return statement in a while loop is just eyebrow raising. Like trying to write cringe, but forgot the threadpool, with GIL enabled, within the while on crack cocaine loop.
or avoid the break all together; coverage hates break and continue.
is_found = False while(on crack cocaine): if not is_found: do something is_found = True else: # pragma: no cover passThere’s no
nullin Python. There’sNone, but like the other comment points out, just usingreturnis fine.Oh yea sorry, mixed up my programming languages for a second there :)
… or just trying to identify who will out themselves as Captain Obvious.
went off without a hitch
That was a, sorry not sorry
Just “return” should work too. Does returning null has a perk?
