本文用Python实现一个“孔雀开屏”的效果,Python也可以这么玩。下面是源码,注释里面的是不同画面的执行代码。
from turtle import *
from random import *
from math import *
myColor=['green', 'yellow','red','purple', 'blue','green', 'orange', 'blue'] #孔雀每环颜色
myR=[180,130,90,60,40,30,20,10] # 孔雀每环半径
myRb=[60, 50,40,30,25,20,15,10]
def init(): #初始化
screensize(500,500)
speed(0)
penup()
def drawcircle(c,r): # 画圆圈
fillcolor(c)
begin_fill()
circle(r)
end_fill()
def peacock(): # 画孔雀
pendown()
for i in range(8):
drawcircle(myColor[i],myR[i])
penup()
def controlR(x):#调整半径比例
for i in range(len(myR)):
myR[i]=myR[i]*x
def run(n,bigR): #最终运行函数,bigR为组合的大图形半径
#注意:right()left()函数按角度计算,三角函数按照弧度计算
angle=2*pi/n
right(90+360/n)
for i in range(n):
x=cos(angle*i)*bigR
y=sin(angle*i)*bigR
goto(x,y)
left(360/n)
peacock()
def run2(n,bigR): #与run()区别:这里是半圆
angle=pi/n
right(90+180/n)
for i in range(n):
x=cos(angle*i)*bigR
y=sin(angle*i)*bigR
goto(x,y)
left(180/n)
peacock()
def run2(n,bigR,scale): #最终运行函数,bigR为组合的大图形半径,scale代表弧度与2pi的比例
#注意:right()left()函数按角度计算,三角函数按照弧度计算
angle=2*pi/n*scale
right(90+360/n*scale)
for i in range(n):
x=cos(angle*i)*bigR
y=sin(angle*i)*bigR
goto(x,y)
