用python的pygame画一个爱心

以下是用Python的pygame库画一个爱心的代码：

import pygame

# 初始化pygame
pygame.init()

# 设置窗口大小和标题
width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Draw Heart with Pygame")

# 定义颜色
red = (255, 0, 0)

# 画爱心
heart_center_x, heart_center_y = width // 2, height // 2
heart_size = 200
heart_thickness = 5
pygame.draw.circle(screen, red, (heart_center_x - heart_size // 4, heart_center_y - heart_size // 4), heart_size // 2, heart_thickness)
pygame.draw.circle(screen, red, (heart_center_x + heart_size // 4, heart_center_y - heart_size // 4), heart_size // 2, heart_thickness)
pygame.draw.polygon(screen, red, [(heart_center_x - heart_size // 2, heart_center_y), (heart_center_x + heart_size // 2, heart_center_y), (heart_center_x, heart_center_y + heart_size // 2)], heart_thickness)

# 刷新屏幕
pygame.display.flip()

# 等待退出
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

运行以上代码，就会在屏幕中央画出一个红色的爱心。可以根据需要调整爱心的大小和颜色等参数。
