Python 蟒蛇3：矩形之间的距离不断变化

创建间距相等但高度和宽度随机的矩形。但是，它们之间的距离不是固定不变的

    import TurtleHelper
    import turtle
    import random as rd


    def drawRectangle(myTurtle, width, height): 
        for i in range(2):
            myTurtle.fd(width)
            myTurtle.left(90)
            myTurtle.fd(height)
            myTurtle.left(90)

    def drawRectangleagain(myTurtle):       
        myTurtle.up()
        myTurtle.forward(100)
        myTurtle.down()





def main():
    window=TurtleHelper.initWindow()
    t=turtle.Turtle()
    t.pencolor("blue")



    for i in range(3):
        drawRectangle(t,rd.randint(20, 60), rd.randint(20, 110))
        drawRectangleagain(t)


    window.exitonclick()
main()

从顶点D开始，在顶点D结束。因此，向前移动100时，一个矩形和下一个矩形之间的距离为

100-DC

。因为DC是一个随机数，所以矩形之间的距离是一个随机数

您可以获得如下一致的间距

def drawRectangle(myTurtle, width, height): 
        for i in range(2):
            myTurtle.fd(width)
            myTurtle.left(90)
            myTurtle.fd(height)
            myTurtle.left(90)
        myTurtle.up()
        myTurtle.fd(width)
