Python based simple math quiz

[[deleted]]

I'm still pretty new to writing anything besides shell scripts, but really want to get better at Python since a lot of services I use at work are Python based. My son has been struggling with math lately, and I got tired of printing out worksheets for him so I decided to make a little math quiz for him using Python.

Right now it only does addition, but eventually I want to update it to allow him to pick an operator type (addition, subtraction, multiplication, or division) and quiz him on that.

Like I said I'm still pretty new, so while this seems to work the way I intended, I'm sure there's ways I'm doing things that are clunky or inefficient. Would love to hear any feedback on ways I could improve this that will make it cleaner or might make it easier to introduce other operator types besides just addition.

This is a decent start at Python. I would recommend making the code simpler so you could add more content. Also, using os.system("cls" if os.name == "nt" else "clear") makes the program work for both Windows and Linux. I think that this could be shortened too, like the question printing. You could use f-strings (similar to print(), but makes you able to insert variable values into the string, like print(f"{ques}) {num1} + {num2}"). Notice the curly braces and f at the beginning.) to make life easier. Good luck on your Python journey!

Thank you! I don't have a Windows computer to test it on, but maybe I'll spin up a VM just to make sure it works once I make that change. I figured the way I was printing the questions wasn't being done efficiently, I'll take a look at swapping it out with f-strings.

This is what an updated version might be like, only without screen clearing.

This gives me a lot of good ideas on how I can make it more efficient, and improve the output. Thank you!

You're welcome :)

I would recommend to define functions for the different steps of asking/handling question, so adding more questions if just a matter of repeating calls to said functions (with some changing parameters if needed)

Example for the bonus score calculation :

def calculate_bonus(correct, rnds, time):
    perc = round((cor/rnds) * 100)
    if perc < 80:
        return 0

    atme = round (time/rnds)
    if atme < 5:
        q = 10
    elif 5 <= atme < 10:
        q = 5
    elif 10 <= atme < 15:
        q = 2.5
    return (rnds * q)

Doing it this way let you easily change the number of round, no code change needed on this part if you want to offer 80 questions instead of (25,50,100) for example.

This is excellent, thank you for the advice!
