math.sqrt()

调用math模块

折线图绘制

import turtle

import math

x1,y1=50,50

x2,y2=50,-50

x3,y3=-50,-50

x4,y4=-50,50

turtle.penup

turtle.goto(x1,y1)

turtle.pendown()

turtle.goto(x2,y2)

turtle.goto(x3,y3)

turtle.goto(x4,y4)

distance=math.

sqrt((x1-x4)**2+(y1=y4)**2) turtle.write(distance)

计算距离：

import math

distance=math.sqrt((x1-x4)**2+(y1-y4)**2)

turtle.write(distance)

【操作】定义多点坐标_绘出折线_并计算起始点和终点距离

import turtle

import math

x1,y1=100,100

x2,y2=100,-100

x3,y3=-100,-100

x4,y4=-100,100

turtle.penup()

turtle.goto(x1,y1)

turtle.pendown()

turtle.goto(x2,y2)

turtle.goto(x3,y3)

turtle.goto(x4,y4)

dis=math.sqrt((x1-x4)**2+(y1-y4)**2)

【操作】定义多点坐标_绘出折线_并计算起始点和终点距离

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)
turtle.write(distance)
