Repeat codes with while loop

I’m having trouble executing a noose while within another while.

I used the code below, which does everything right, but at the time I type 1 it only repeats the question "Do you want to repeat? type 1 for yes and 2 for no:", and I want you to repeat the whole program but it just repeats the last sentence.

resp = int(1)

n1 = -1

n2 = -1

while resp == 1:

    while n1 > 10 or n1 < 0:
        n1 = float(input("Qual valor da sua primeira nota?: "))
        if n1 > 10 or n1 < 0:
            print('Nota invalida.')
    while n2 > 10 or n2 < 0:
        n2 = float(input("Qual valor da sua segunda nota?: "))
        if n2 > 10 or n2 < 0:
            print('Nota invalida.')
        media = (n1 + n2) / 2
        print('A sua média foi de {}'.format(media))
    resp = int(input('Deseja repetir? digite 1 para sim e 2 para não: '))
python while

  • This happens because the n1 and n2 continue with the entered value, reset the two variables after the question "Want to repeat?"

Before when the program ran out if the user wanted to run it again could not, because it did not enter the loops while n1 > 10 or n1 < 0 and while n1 > 10 or n1 < 0, due to the fact that the condition in the loops is false, because at the end of the program the variables n1 and n2 would be with a value below 10 and above 0, there are 2 ways to fix this:

1 - Maintaining the structure of your code (resetting variables when the program runs again)

resp = int(1)
n1 = -1
n2 = -1

while resp == 1:

    if resp == 2:
        n1 = -1
        n2 = -1

    while n1 > 10 or n1 < 0:
        n1 = float(input("Qual valor da sua primeira nota?: "))
        if n1 > 10 or n1 < 0:
            print('Nota invalida.')

    while n2 > 10 or n2 < 0:
        n2 = float(input("Qual valor da sua segunda nota?: "))
        if n2 > 10 or n2 < 0:
            print('Nota invalida.')

    media = (n1 + n2) / 2
    print('A sua média foi de {}'.format(media))
    resp = int(input('Deseja repetir? digite 1 para sim e 2 para não: '))

2 - Pythonic shape, visually more beautiful/pleasant and easy to understand:

resp = 1

while resp == 1:

    while True:
        n1 = float(input("Qual valor da sua primeira nota?: "))
        if n1 > 10 or n1 < 0:
            print('Nota invalida.')
        else:
            break

    while True:
        n2 = float(input("Qual valor da sua segunda nota?: "))
        if n2 > 10 or n2 < 0:
            print('Nota invalida.')
        else:
            break

    media = n1 + n2 / 2
    print(f'A sua média foi de {media}')
    # Se estiver usando o python 3.6 ou inferior utilize: print('A sua média foi de {}'.format(media))
    resp = int(input('Deseja repetir? digite 1 para sim e 2 para não: '))
