[Python知识库]Python-简易乌龟绘图（计算两点距离）

import turtle
import math
#定义多个点坐标
x1,y1 = 100,100
x2,y2 = 100,-100
x3,y3 = -100,-100
x4,y4 = -100,100
#绘制路径
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) #sqrt() 表示平方根
turtle.write(distance)
