5、黑白树

这个比较复杂,画的工夫较长

from turtle import *

设置色调模式是 RGB:

colormode(255)
lt(90)
lv = 14
l = 120
s = 45
width(lv)

初始化 RGB 色彩:

r = 0
g = 0
b = 0
pencolor(r, g, b)
penup()
bk(l)
pendown()
fd(l)
def draw_tree(l, level):

global r, g, b
# save the current pen width
w = width()
# narrow the pen width
width(w * 3.0 / 4.0)
# set color:
r = r + 1
g = g + 2
b = b + 3
pencolor(r % 200, g % 200, b % 200)
l = 3.0 / 4.0 * l
lt(s)
fd(l)
if level < lv:
    draw_tree(l, level + 1)
bk(l)
rt(2 * s)
fd(l)
if level < lv:
    draw_tree(l, level + 1)
bk(l)
lt(s)
# restore the previous pen width
width(w)

speed(“fastest”)
draw_tree(l, 4)
done()
