用python画一棵樱花树

好的，我可以回答这个问题。以下是使用 Python 绘制樱花树的示例代码：

import turtle
import random

# 设置画布大小
turtle.setup(width=800, height=600)

# 设置画笔大小和颜色
turtle.pensize(3)
turtle.pencolor("brown")

# 定义函数：绘制树干
def draw_trunk():
    turtle.pendown()
    turtle.right(90)
    turtle.forward(100)

# 定义函数：绘制树枝
def draw_branch(branch_length):
    if branch_length > 5:
        turtle.forward(branch_length)
        turtle.right(random.randint(15, 45))
        draw_branch(branch_length - random.randint(10, 20))
        turtle.left(random.randint(15, 45))
        draw_branch(branch_length - random.randint(10, 20))
        turtle.right(random.randint(15, 45))
        turtle.backward(branch_length)

# 定义函数：绘制樱花
def draw_cherry_blossom():
    turtle.pencolor("pink")
    turtle.penup()
    turtle.setpos(random.randint(-350, 350), random.randint(50, 250))
    turtle.pendown()
    turtle.begin_fill()
    turtle.circle(random.randint(10, 30))
    turtle.end_fill()

# 绘制樱花树
draw_trunk()
draw_branch(60)
draw_cherry_blossom()

# 隐藏画笔
turtle.hideturtle()

# 点击关闭窗口
turtle.exitonclick()

这是一段基于 Turtle 库的示例代码，可以绘制出一个随机的樱花树。希望能够帮到你。
