Python怎样画出一颗美丽的樱花树？
要用Python画下代码画，首先需要安装turtle库，然后输入以下代码，即可画出漂亮的樱花树了！
效果图：
漂亮的樱花树(动态)
源代码如下：
import turtle as tu
import random
import time
def Tree(branch, t):
time.sleep(0.0005)
if branch > 3:
if 8 <= branch <= 12:
if random.randint(0, 2) == 0:
t.color('snow')
else:
t.color('lightcoral')
t.pensize(branch / 3)
elif branch < 8:
if random.randint(0, 1) == 0:
t.color('snow')
else:
t.color('lightcoral')
t.pensize(branch / 2)
else:
t.color('sienna')
t.pensize(branch / 10)
t.forward(branch)
a = 1.5 * random.random()
t.right(20 * a)
b = 1.5 * random.random()
Tree(branch - 10 * b, t)
t.left(40 * a)
Tree(branch - 10 * b, t)
t.right(20 * a)
t.up()
t.backward(branch)
t.down()
def Petal(m, t):
for i in range(m):
a = 200 - 400 * random.random()
b = 10 - 20 * random.random()
t.up()
t.forward(b)
t.left(90)
t.forward(a)
t.down()
t.color('lightcoral')
t.circle(1)
t.up()
t.backward(a)
t.right(90)
t.backward(b)
t = tu.Turtle()
w = tu.Screen()
t.hideturtle()
t.getscreen().tracer(5, 0)
w.screensize(bg='wheat')
t.left(90)
t.up()
t.backward(150)
t.down()
t.color('sienna')
Tree(60, t)
Petal(200, t)
w.exitonclick()
