定义多点坐标,绘出折现,计算距离:
import turtle
import math
#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)
***2代表平方
turtle.write(distance)
