给孩子们上课用的一个例子,先要讲一下函数与如何使用coloradd模块及安装方法。

import turtle
from coloradd import colorset
from winsound import PlaySound,SND_LOOP,SND_ASYNC

def setcolor():
    d = turtle.distance(0,0)+ 10
    c = colorset(d)                         # 把整数转换成RGB颜色三元组
    turtle.color(c)

def draw_miao(step):
    for _ in range(7):
        setcolor()
        turtle.fd(step);turtle.dot(10,'red')
        turtle.rt(15)
    for _ in range(7):
        setcolor()
        turtle.lt(15)
        turtle.bk(step)       
    for _ in range(7):
        setcolor()
        turtle.fd(step);turtle.dot(10,'red')
        turtle.lt(15)
    for _ in range(7):
        setcolor()
        turtle.rt(15)
        turtle.bk(step)       

turtle.delay(0)
turtle.speed(0)
turtle.pensize(1)
turtle.colormode(255)
turtle.bgcolor('black') 
PlaySound('11.wav',SND_LOOP|SND_ASYNC)
for _ in range(45):    
    draw_miao(30)        
    turtle.rt(8)

turtle.done()
