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 orange(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);
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)

运行结果及报错内容 NameError: name 'orange' is not defined，
