【python】turtle龟绘制开了花朵的树,程序画图
天啊,没想到python龟绘制的图居然这么美腻!
代码传送门:
import turtle
import random
from turtle import *
from time import sleep
t = turtle.Turtle()
w = turtle.Screen()
def tree(branchLen, t):
if branchLen > 3:
if 8 <= branchLen <= 12:
if random.randint(0, 2) == 0:
t.color('snow')
else:
t.color('lightcoral')
t.pensize(branchLen / 3)
elif branchLen < 8:
if random.randint(0, 1) == 0:
t.color('snow')
else:
t.color('lightcoral')
t.pensize(branchLen / 2)
else:
t.color('sienna')
t.pensize(branchLen / 10)
t.forward(branchLen)
a = 1.5 * random.random()
t.right(20*a)
b = 1.5 * random.random()
tree(branchLen-10*b, t)
t.left(40*a)
tree(branchLen-10*b, t)
t.right(20*a)
t.up()
t.backward(branchLen)
t.down()
def petal(m, t): # 树下花瓣
for i in range(m):
a = 200 - 400 * random.random()
b = 10 - 20 * random.random()
t.up()
t.forward(b)
t.left(90)
t.forward(a)
t.down()
t.color("lightcoral")
t.circle(1)
t.up()
t.backward(a)
t.right(90)
t.backward(b)
def main():
t = turtle.Turtle()
myWin = turtle.Screen()
getscreen().tracer(5, 0)
turtle.screensize(bg='wheat')
t.left(90)
t.up()
t.backward(150)
t.down()
t.color('sienna')
tree(60, t)
petal(100, t)
myWin.exitonclick()
main()
效果图:
不要问为什么每次画的花都不一样
问就是因为python龟它有自己的思想!(random)
试试看吧,真的是太美腻了,现在正好是樱花盛开的季节呢~
