代码如下：

 

 

from turtle import *
import random
import time
n=80.0
speed('fastest')
screensize(bg='pink')
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)
t.color('dark red','red')

t.done
time.sleep(60)

代码结果：
