用Python画出奥运五环图 （Python经典编程案例）

1. 画出奥运五环图，代码如下：

import turtle
turtle.width(10)
turtle.color("blue")
turtle.circle(50)

turtle.color("black")
turtle.penup()
turtle.goto(120, 0)
turtle.pendown()
turtle.circle(50)

turtle.color("red")
turtle.penup()
turtle.goto(240, 0)
turtle.pendown()
turtle.circle(50)

turtle.color("yellow")
turtle.penup()
turtle.goto(60, -50)
turtle.pendown()
turtle.circle(50)

turtle.color("green")
turtle.penup()
turtle.goto(180, -50)
turtle.pendown()
turtle.circle(50)

执行结果如下图所示：

2. 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)
