源代码

from turtle import *
import random
import time
#from unittest.mock import right
#import color as color
#import down as down
#from cv2.cv2 import circle
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)
write("author：超哥。圣诞节快乐！！！", move=True, align="left", font=("宋体", 30, "normal"))
done()
