【问题描述】：
我正在尝试为我的班级做一个测验，允许用户参加测验，但仅限于海龟图形，因此测验问题将出现在海龟图形屏幕中，他们将通过按选择他们想要的答案屏幕上标有 a、b、c 或 d 的部分。我遇到的问题是，当用户选择他们的选择并且我不知道turtle.listen 是如何工作时，我不知道如何出现新问题。有任何想法吗？
这是我目前所拥有的：

x = turtle.xcor()
y = turtle.ycor()

Griffindor = 0
Hufflepuff = 0
Ravenclaw = 0

turtle.penup()
turtle.goto(10,150)
turtle.write("\n This code is a quiz that will determine what Hogwart house you belong in:\n Slytherin, Griffindor, Hufflepuff, or Ravenclaw! \n \n You will be asked quiz questions on this screen, and then \n when you want to answer, you tell the program \n what you chose by pressing the corresponding section. \n", align = "center" , font=("Arial", 20, "normal"))
