pygame实现加法计算器

可以使用pygame实现一个简单的加法计算器，以下是示例代码：

import pygame

pygame.init()

# 设置窗口大小和标题
win = pygame.display.set_mode((400, 300))
pygame.display.set_caption("加法计算器")

# 设置字体
font = pygame.font.SysFont("Arial", 30)

# 初始化变量
num1 = ""
num2 = ""
result = ""

# 游戏循环
run = True
while run:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
        elif event.type == pygame.KEYDOWN:
            if event.unicode.isdigit():
                if len(num1) < 10:
                    num1 += event.unicode
            elif event.key == pygame.K_BACKSPACE:
                num1 = num1[:-1]
            elif event.key == pygame.K_RETURN:
                if num1 and num2:
                    result = str(int(num1) + int(num2))
                else:
                    result = ""
            elif event.key == pygame.K_ESCAPE:
                num1 = ""
                num2 = ""
                result = ""
            else:
                pass

    # 绘制界面
    win.fill((255, 255, 255))
    text1 = font.render(num1, True, (0, 0, 0))
    text2 = font.render(num2, True, (0, 0, 0))
    text3 = font.render(result, True, (0, 0, 0))
    win.blit(text1, (50, 50))
    win.blit(text2, (50, 100))
    win.blit(font.render("+", True, (0, 0, 0)), (150, 75))
    win.blit(text3, (200, 75))
    pygame.display.update()

pygame.quit()

这个加法计算器可以接受用户输入两个数字，按下回车键后会计算它们的和并显示在屏幕上。按下 ESC 键可以清空输入。
