代码如下:
from turtle import *
import random
import time n = 80.0 speed("fastest")
screensize(bg='seashell')
left(90)
forward(3*n)
color("orange", "yellow")
begin_fill()
left(126) for i in range(5):
forward(n/5)
right(144)
forward(n/5)
left(72)
end_fill()
right(126) color("dark green")
backward(n*4.8)
def tree(d, s):
if d <= 0: return
forward(s)
tree(d-1, s*.8)
right(120)
tree(d-3, s*.5)
right(120)
tree(d-3, s*.5)
right(120)
backward(s)
tree(15, n)
backward(n/2) for i in range(200):
a = 200 - 400 * random.random()
b = 10 - 20 * random.random()
up()
forward(b)
left(90)
forward(a)
down()
if random.randint(0, 1) == 0:
color('tomato')
else:
color('wheat')
circle(2)
up()
backward(a)
right(90)
backward(b)
time.sleep(60)
效果图如下:
