#定义多个点的坐标
x1,y1 = 100,100
x2,y2 = 100,-100
x3,y3 = -100,-100
x4,y4 = -100,100

#绘制折线
turtle.penup()
turtle.goto(x1,y1)
turtle.pendown()

turtle.goto(x2,y2)
turtle.goto(x3,y3)
turtle.goto(x4,y4)

#计算起始点和终点的距离
distance = math.sqrt((x1 - x4)**2 + (y1 -y4)**2)
turtle.write(distance)

#填充结束
turtle.end_fill()
#不会退出，而是等待
turtle.mainloop()
