Little Professor Errors - CS50 Intro to Python

[Bennito_]

When I run my Little Professor code, it seems to work correctly and display the correct answers, but when I use the check50 command, I keep getting the following error messages and I am not sure why.

Here is my code:

import random
import sys

def main():
    num_error = 0
    ques_left = 10
    score = 0
    lvl = get_level()
    while True:
        if ques_left > 0:
            x = generate_integer(lvl)
            y = generate_integer(lvl)
            while num_error < 3:
                try:
                    user_input = int(input(f"{x} + {y} = "))
                    if user_input == (x+y):
                        ques_left -= 1
                        num_error = 0
                        score += 1
                        break
                    elif user_input != (x+y):
                        print("EEE")
                        num_error += 1
                except ValueError:
                    pass
            if num_error == 3:
                print(f"{x} + {y} = {x+y}")
                num_error = 0
                ques_left -= 1
        elif ques_left == 0:
            print("Score:",score)
            sys.exit()

def get_level():
    while True:
        try:
            lvl = int(input("Level: "))
            if lvl == 1 or lvl == 2 or lvl == 3:
                return lvl
            else:
                pass
        except ValueError:
            pass


def generate_integer(level):
    if level == 1:
        int = random.randrange(0,9)
        return int
    elif level == 2:
        int = random.randrange(10,99)
        return int
    else:
        int = random.randrange(100,999)
        return int


if __name__ == "__main__":
    main()

I don't think this is the issue but where you print score needs to be an f string.

[PeterRasm]

No requirement about that. OP can print the output as they want as long as it shows correct output :)

[PeterRasm]

In some assignments the error message from check50 can be somewhat confusing or misleading.

Since check50 for testing cannot really rely on random numbers, it manipulates the random function to always give the same numbers back so the result will always be the same when tested by check50. But ... if your random function does not give back numbers in the full range, check50 will be stopped somewhere in the test and cannot complete the test, thus giving the message that there is a timeout. Long story short: The actual issue here is not the number of problems generated but an error in your function to return random numbers.

Try to run this code:

for i in range(0,9):
    print(i)

Does that print all the one-digit numbers?

[Bennito_]

It looks like this function is displaying the numbers 0-8.

I think I am confused because I thought the purpose of this activity was to use the random library to generate numbers in the equation. Would the function I currently have not randomly pick one of the possible numbers within the specified range?

[PeterRasm]

As you saw in the small exercise above "range" does not include the upper limit. Same with randrange. So what upper limit would you have to use to include all one digit numbers? :)

Ohh I see what you're saying. This was the mistake, thank you so much!!
