用turtle画樱花树

好的，以下是用Python的turtle库来画樱花树的代码：

import turtle
import random

# 设置画布大小和背景颜色
turtle.setup(800, 600)
turtle.bgcolor("#F8F8FF")

# 设置画笔宽度和颜色
turtle.penup()
turtle.pensize(3)
turtle.color("#8B0000")

# 定义函数来画樱花
def draw_flower():
    turtle.right(random.randint(0, 360))
    turtle.forward(random.randint(10, 30))
    turtle.right(random.randint(0, 360))
    turtle.pendown()
    turtle.color("#FF69B4")
    turtle.begin_fill()
    turtle.circle(random.randint(5, 10))
    turtle.end_fill()
    turtle.penup()
    turtle.color("#8B0000")
    turtle.right(random.randint(0, 360))
    turtle.backward(random.randint(10, 30))

# 画樱花树
turtle.goto(0, -250)
turtle.pendown()
turtle.left(90)
turtle.forward(150)
turtle.right(135)
turtle.forward(200)
turtle.left(135)
turtle.forward(200)
turtle.right(135)
turtle.forward(200)
turtle.left(135)
turtle.forward(200)
turtle.right(135)
turtle.forward(150)

# 画樱花
turtle.goto(0, 0)
for i in range(100):
    draw_flower()

# 隐藏画笔
turtle.hideturtle()

# 点击关闭窗口
turtle.exitonclick()

运行上述代码，即可在turtle窗口中看到画出的樱花树。效果如下图所示：
