动态圣诞树代码编程python

以下是一个简单的动态圣诞树代码示例，使用Python的turtle模块绘制：

import turtle

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("black")
pen = turtle.Turtle()
pen.speed(0)

# 绘制圣诞树
def draw_tree(size, levels):
    if levels == 0:
        return
    else:
        pen.color("green")
        pen.forward(size)
        pen.left(45)
        draw_tree(0.6 * size, levels - 1)
        
        pen.right(90)
        draw_tree(0.6 * size, levels - 1)
        
        pen.left(45)
        pen.backward(size)

# 绘制圣诞树的装饰
def draw_decorations(size, levels):
    if levels == 0:
        return
    else:
        pen.color("red")
        pen.forward(size)
        pen.left(45)
        draw_decorations(0.6 * size, levels - 1)
        
        pen.right(90)
        draw_decorations(0.6 * size, levels - 1)
        
        pen.left(45)
        pen.backward(size)

# 绘制圣诞树的星星
def draw_star():
    pen.color("yellow")
    pen.penup()
    pen.goto(0, 200)
    pen.pendown()
    pen.begin_fill()
    for _ in range(5):
        pen.forward(50)
        pen.right(144)
    pen.end_fill()

# 绘制整个圣诞树
def draw_christmas_tree():
    pen.penup()
    pen.goto(0, -200)
    pen.pendown()
    pen.left(90)
    draw_tree(100, 7)
    draw_decorations(100, 7)
    draw_star()

# 调用绘制函数
draw_christmas_tree()

# 隐藏画笔
pen.hideturtle()

# 结束绘制
turtle.done()
