Python樱花树源代码

以下是Python实现樱花树的代码。

import turtle
import random

# 定义花瓣颜色列表
colorList = ['pink', 'lightPink', 'hotPink', 'deepPink', 'paleVioletRed', 'mediumVioletRed']

# 定义花朵的大小和颜色
def drawFlower(size, color):
    turtle.speed(0)
    turtle.penup()
    turtle.forward(size)
    turtle.left(90)
    turtle.pendown()
    turtle.color(color)
    turtle.begin_fill()
    turtle.circle(size/2, 180)
    turtle.circle(size/4, 180)
    turtle.end_fill()
    turtle.right(90)
    turtle.penup()
    turtle.backward(size)
    
# 定义画樱花树的递归函数
def drawTree(branchLen):
    if branchLen > 3:
        # 随机设置笔的颜色和宽度
        turtle.pensize(random.uniform(1, 5))
        turtle.color('brown')
        # 绘制主干
        turtle.forward(branchLen)
        turtle.right(20)
        drawTree(branchLen-random.uniform(15, 25))
        turtle.left(40)
        drawTree(branchLen-random.uniform(15, 25))
        turtle.right(20)
        turtle.backward(branchLen)
        # 绘制花朵
        if branchLen <= 40:
            flowerSize = random.uniform(5, 10)
            flowerColor = random.choice(colorList)
            drawFlower(flowerSize, flowerColor)

# 设置画布和画笔
turtle.Screen().setup(width=800, height=600)
turtle.Screen().bgcolor('lightBlue')
turtle.left(90)
turtle.penup()
turtle.backward(200)
turtle.pendown()

# 开始绘制樱花树
drawTree(100)

# 隐藏画笔
turtle.hideturtle()

# 点击关闭窗口
turtle.done()

运行代码后，会弹出一个窗口，显示绘制的樱花树。点击窗口后，程序会退出。
