我怎么能关闭一个while循环，在我回答10个问题后进行的测验？

Question

while True:
    if play.lower() == "yes":
        print("great, here we go!")

        first = random.randint(1, 10)
        second = random.randint(1, 20)

        questionA=input("what is" + str(first) + "+" + str(second))

        userAnswer = first + second

        if userAnswer == userAnswer:
            print("well done")


    elif play.lower() == "no":
        print("ok goodbye")

您可以通过使用某种变量来解决这个问题，该变量可以跟踪问题的数量。例如：在下面的代码片段中，检查noOfQuestions是否等于或小于10，如果是，则执行while循环，否则不执行。

<强>代码：

noOfQuestions = 1
while noOfQuestions<=10: #<-- check if noOfQuestions is less than or equal to 10
    print noOfQuestions
    noOfQuestions += 1 #<--- update the noOfQuestions variable
else:
    print ("noOfQuestions is %d.")%noOfQuestions
