Python while循环，我被困住了！ ：C

Question

我是编程新手（3 天前刚开始），我需要有关此代码的帮助，我真的需要。

我不知道如何执行while 循环。 （在#### 行下方）。你能帮帮我吗？

我正在使用python 3.4.2 版

import random

right = 0
wrong = 0

for i in range(10):

        x = random.randint (2,29)
        y = random.randint (3,29)
        z = (x*y)
        qq = input("What's " + str(x) + " times " + str(y) + "? ")


        if   str(z) == str(qq):
             right = right +1
             print ("Correct!\n")

        else:
            wrong = wrong + 1
            print ("Wrong the correct answer is ",str(z),"\n")


print ("You got", right, "out of 10 questions")

if right==10:
        print ("Well Done! Perfect score!")

elif right>=5:
        print ("Well done! try getting perfect score next time")

else:
        print ("Noob")
#################################################
restart = y
while True:
        yess = input ("Would you like to try again? y/n?")
        if restart == yess:
                print (i)
        else:
                break

以下是该问题的快速解决方法：

import random

while True:    
    right = 0
    wrong = 0

    for i in range(10):

            x = random.randint (2,29)
            y = random.randint (3,29)
            z = (x*y)
            qq = input("What's " + str(x) + " times " + str(y) + "? ")


            if   str(z) == str(qq):
                 right = right +1
                 print ("Correct!\n")

            else:
                wrong = wrong + 1
                print ("Wrong the correct answer is ",str(z),"\n")


    print ("You got", right, "out of 10 questions")

    if right==10:
            print ("Well Done! Perfect score!")

    elif right>=5:
            print ("Well done! try getting perfect score next time")

    else:
            print ("Noob")
    #################################################
    restart = "y"
    yess = input ("Would you like to try again? y/n?")
    if restart != yess:
        break;

基本上，您只需将整个代码放入 while 循环中，这样它就会真正重复。

另外，老实说，当我将"y" 放在引号中以使其成为字符串时，我真的希望我没有搞砸。一个多小时没接触 Python，所以对语法有些模糊。
