Question

我将在几个小时内完成作业，而且我不知道该做什么。我正在使用python 3。

我一直在尝试运行代码，但是我遇到了错误。在这一点上，我想我会寻求帮助。

提前谢谢你！

你的测试代码很乱，你不需要多只乌龟，只需要一条，就行了：

def main():

    listofcolors = ("blue", "red", "yellow", "orange", "pink", "green")
    wn = turtle.Screen()
    mr = myRectangle(0, 0, 100, 100, "blue")
    phil = turtle.Turtle()

    for _ in range(6):
        x = random.randint(-200, 200)
        print(x)
        y = random.randint(-200, 200)
        print(y)
        w = random.randint(1, 150)
        print(w)
        h = random.randint(1, 150)
        print(h)
        c = random.choice(listofcolors)
        print(c)

        mr.setX(x)
        mr.setY(y)
        mr.setWidth(w)
        mr.setHeight(h)
        mr.setColor(c)

        mr.draw(phil)

    wn.mainloop()

main()

这会让您按照说明进入第7步。

我不知道你的__var__()函数应该做什么，这似乎是一个冗长的无操作。您的draw()功能略有调整：

    def draw(self, turtle):
        turtle.penup()
        turtle.goto(self.getX(), self.getY())
        turtle.setheading(0)
        turtle.color(self.getColor())  # set both pen & fill color
        turtle.pendown()
        turtle.begin_fill()
        turtle.forward(self.__width)
        turtle.left(90)
        turtle.forward(self.__height)
        turtle.left(90)
        turtle.forward(self.__width)
        turtle.left(90)
        turtle.forward(self.__height)
        turtle.left(90)
        turtle.end_fill()

问题是您在帖子中粘贴的代码与您列出的文件中的代码不同。在文件中，第92行有一个错误，你没有向setColor提供任何参数：
