python+动态代码

以下是一个使用Python的turtle库绘制动态满屏爱心的例子：

import turtle

# 创建一个画布
canvas = turtle.Screen()
canvas.bgcolor("black")

# 创建一个画笔
pen = turtle.Turtle()
pen.shape("turtle")
pen.color("red")
pen.speed(0)

# 定义爱心的形状
def draw_heart():
    pen.begin_fill()
    pen.left(140)
    pen.forward(224)
    for i in range(200):
        pen.right(1)
        pen.forward(2)
    pen.forward(224)
    pen.left(140)
    pen.end_fill()

# 移动到指定位置
def move_to(x, y):
    pen.penup()
    pen.goto(x, y)
    pen.pendown()

# 定义爱心的移动和移动到某点的函数
def move_heart():
    for i in range(360):
        pen.right(1)
        pen.forward(2)

# 定义爱心的移动速度和颜色与大小相关
def set_speed_color_size(speed, color, size):
    pen.speed(speed)
    pen.color(color)
    pen.pensize(size)

# 绘制动态满屏爱心
def draw_dynamic_hearts():
    for i in range(100):
        move_to(0, 0)
        set_speed_color_size(10, "red", 2)
        draw_heart()
        move_heart()

# 调用函数绘制动态满屏爱心
draw_dynamic_hearts()

# 结束绘制
turtle.done()
