动态美丽圣诞树python

以下是一个使用Python的海龟模块绘制动态美丽圣诞树的例子：

import turtle

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("black")
pen = turtle.Turtle()
pen.speed(10)

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

# 绘制圣诞树的装饰
def draw_decorations():
    pen.color("red")
    pen.penup()
    pen.goto(0, -200)
    pen.pendown()
    pen.begin_fill()
    pen.circle(20)
    pen.end_fill()

    pen.color("yellow")
    pen.penup()
    pen.goto(0, -180)
    pen.pendown()
    pen.begin_fill()
    pen.circle(15)
    pen.end_fill()

    pen.color("blue")
    pen.penup()
    pen.goto(0, -160)
    pen.pendown()
    pen.begin_fill()
    pen.circle(10)
    pen.end_fill()

# 绘制圣诞树的礼物
def draw_gift():
    pen.color("red")
    pen.penup()
    pen.goto(-50, -200)
    pen.pendown()
    pen.begin_fill()
    pen.forward(100)
    pen.left(90)
    pen.forward(50)
    pen.left(90)
    pen.forward(100)
    pen.left(90)
    pen.forward(50)
    pen.left(90)
    pen.end_fill()

# 绘制圣诞树的星星
def draw_star():
    pen.color("yellow")
    pen.penup()
    pen.goto(-10, 100)
    pen.pendown()
    pen.begin_fill()
    for _ in range(5):
        pen.forward(20)
        pen.right(144)
    pen.end_fill()

# 调用函数绘制圣诞树
draw_tree(100, 5)
draw_decorations()
draw_gift()
draw_star()

# 隐藏画笔
pen.hideturtle()

# 结束绘制
turtle.done()

这段代码使用了海龟模块来绘制圣诞树的图案，包括树干、树枝、装饰品、礼物和星星等元素。你可以根据自己的喜好调整颜色、大小和层级等参数来绘制出你喜欢的动态美丽圣诞树。
