Python学习笔记：好玩的图形Python代码1、绘制多彩圆圈
import turtle
colors = ["red","orange","yellow","green","blue","indigo","purple",'black']#颜⾊
for i in range(len(colors)):#循环画8个
c = colors[i]
turtle.begin_fill()
turtle.circle(100)
<(360/len(colors))#分割⼋次
turtle.done()
2、画时钟
import turtle
from datetime import *
# 抬起画笔，向前运动⼀段距离放下
def Skip(step):
turtle.penup()
turtle.forward(step)
turtle.pendown()
def mkHand(name, length):
# 注册Turtle形状，建⽴表针Turtle
python新手代码图案如何保存set()
Skip(-length * 0.1)
# 开始记录多边形的顶点。当前的乌龟位置是多边形的第⼀个顶点。
turtle.begin_poly()
turtle.forward(length * 1.1)
# 停⽌记录多边形的顶点。当前的乌龟位置是多边形的最后⼀个顶点。将与第⼀个顶点相连。
# 返回最后记录的多边形。
handForm = _poly()
def Init():
global secHand, minHand, hurHand, printer
# 重置Turtle指向北
# 建⽴三个表针Turtle并初始化
