[python趣味实战]----python动态爱心代码

下面是一个使用Python的turtle库来绘制动态爱心的示例代码：

import turtle
import math
 
# 设置屏幕
screen = turtle.Screen()
screen.bgcolor("black")
screen.title("动态爱心")
 
# 设置爱心参数
heart_color = "red"
heart_size = 8
heart_speed = 0.05
 
# 绘制爱心函数
def draw_heart(t, size, x, y):
    t.penup()
    t.goto(x, y)
    t.pendown()
    t.color(heart_color)
    t.startfill()
 
    a = size * 0.5522847498307933
    t.left(40)
    t.begin_poly()
    for i in range(24):
        if 0 <= i < 12:
            t.left(30)
            t.forward(a)
            t.right(50)
            t.forward(a)
        else:
            t.left(30)
            t.forward(a)
            t.right(40)
            t.forward(a)
    t.end_poly()
    heart_points = t.get_poly()
    t.fillcolor(heart_color)
    t.endfill()
 
# 创建爱心对象
heart = turtle.Turtle()
draw_heart(heart, heart_size, 0, 0)
 
# 心跳动画
def beat():
    for i in range(24):
        t = heart_speed * (24 - i) / 24
        heart.speed(99)
        heart.setx(math.cos(t * 2 * math.pi) * (heart_size + 50))
        heart.sety(math.sin(t * 2 * math.pi) * (heart_size + 50))
        screen.update()
 
# 启动心跳动画
beat()
 
# 保持屏幕打开
screen.mainloop()

这段代码会创建一个动态的爱心在屏幕上跳动。你可以通过调整heart_size、heart_color和heart_speed变量来改变爱心的大小、颜色和速度。
