储存正确答案并保存

Question

我不熟悉堆栈溢出，最近才开始学习Python编程。我目前使用的是python2.7，因此与pythonv3相比，我的代码会有所不同。在

总之，我决定写一个程序，让我的侄子和侄女试用一下。创建的程序是一个数学测试。在

代码可能不是最好的或紧凑的，因为它应该是，但这是我的第一次尝试。在

我附上了我迄今为止在这里键入的代码。请让我知道你的想法和任何反馈。在

我的主要问题是：

• 我想将用户输入的正确答案存储在变量中。然后我希望能够输出用户在测试结束时正确回答的问题的数量。在

例如，如果用户决定接受5个问题集的挑战，得到3个正确答案，我希望程序输出，你得到3/5的正确答案。我有一种感觉，这将是一个非常简单的事情，但我还没有想到。在

我试着创建一个变量，比如answerscorect=0，然后只要answerscorect+=1，每次答案正确时都会递增，但我似乎无法使它起作用，所以我就不做了。在

对此有什么建议吗？在

您需要注意将语句放在何处，以确定它们是否在ifs和循环中。以下是正确的加法代码，其他代码类似：

def addition():
    problems = int(input("How many problems do you want to solve?\n"))

    random.seed()
    count = 0
    answersRight = 0

    while count < problems:
        num_1 = randint(1,12)
        num_2 = randint(1,12)

        userAnswer = int(input("What is " + str(num_1) + "+" + str(num_2) + "? "))
        generatedAnswer = (num_1 + num_2)

        if userAnswer == generatedAnswer:
            print "Correct"
            answersRight += 1
        else:
            print "Sorry, the answer is ", generatedAnswer, "\n"
        count += 1

        print "running score of answers right ", answersRight, " out of ", problems

    start()
