在Python中遇到随机数问题

Question

这是我的代码片段。它一直说用户不正确。每个问题的答案在列表中的顺序相同。

问题库

        questions = ["45 - 20","32 - 12","54 + 41"]

        # Answer Bank
        answers = ["25","20","95"]


        while qleft != 0:


            # Get random question
            qnumber = randint(0,2)
            currentquestion = questions[qnumber]
            currentanswer = answers[qnumber]

            # Question
            userchoice = int(input("What does {} equal? ".format(currentquestion)))

            # Check Answer
            if userchoice != currentanswer:
                print("Incorrect")
                qleft -= 1
            elif userchoice == currentanswer:
                print("Correct")
                qleft -= 1

            else:
                print("That's not a valid answer")

Answer 1

您正在将int输入与str答案进行比较，这些答案永远不会相等。

如果您想处理整体，请更改

answers = ["25","20","95"]

到

answers = [25,20,95]

并且它将起作用。

或者，请勿将input()的结果转换为int。

Answer 2

用户的答案userchoice是一个整数，但实际答案currentanswer是一个字符串。如果您只是将输入保留为字符串，它将起作用：

    questions = ["45 - 20","32 - 12","54 + 41"]

    # Answer Bank
    answers = ["25","20","95"]


    while qleft != 0:


        # Get random question
        qnumber = randint(0,2)
        currentquestion = questions[qnumber]
        currentanswer = answers[qnumber]

        # Question
        userchoice = input("What does {} equal? ".format(currentquestion))

        # Check Answer
        if userchoice != currentanswer:
            print("Incorrect")
            qleft -= 1
        elif userchoice == currentanswer:
            print("Correct")
            qleft -= 1

        else:
            print("That's not a valid answer")

Answer 3

区别在于：

    import random as r

    questions = ["45 - 20","32 - 12","54 + 41"]

    # Answer Bank
    answers = [25,20,95]

    qleft = 3

    while qleft != 0:


        # Get random question
        qnumber = r.randint(0,2)
        currentquestion = questions[qnumber]
        currentanswer = answers[qnumber]

        # Question
        userchoice = int(input("What does {} equal? ".format(currentquestion)))

        # Check Answer
        if userchoice != currentanswer:
            print("Incorrect")
            qleft -= 1
        elif userchoice == currentanswer:
            print("Correct")
            qleft -= 1

        else:
            print("That's not a valid answer")

注意＆＃34; 25＆＃34; ！= 25

Answer 4

由于您要将用户的答案转换为int，因此正确的答案也必须是int。否则，您将字符串与int进行比较，它永远不会相等。
