本文介绍使用Python和PyQt5库开发24点小游戏的完整过程。游戏支持A、J、Q、K对应1、11、12、13，玩家需在限定时间内通过加减乘除及括号组合四个随机抽取的数字得出24。系统包含计分、生命值管理及成绩汇总功能，提供完整的界面设计与逻辑实现代码供参考。

本文分享了一个使用Python编写的24点游戏实例代码，供读者参考学习。

游戏规则如下：一副牌中的A、J、Q、K分别代表数字1、11、12、13。系统随机抽取4张牌，玩家需利用加、减、乘、除运算（允许使用括号）将牌面数字计算为24。每张牌对应的数字必须且只能使用一次。游戏设有时间限制，输入正确算式得10分，输入错误则扣除1点生命值。界面包含“确定”按钮用于提交答案并进入下一题，“清空”按钮用于重置当前算式，“开始游戏”按钮用于启动或重启游戏。

if __name__ == "__main__":

 cardNum = [] # 存放随机牌组
 cardGroup = () # 调用牌组

 app = QtWidgets.QApplication(sys.argv)
 Form = QtWidgets.QMainWindow()
 ui = Ui_Form()
 ui.setupUi(Form)
 Form.show()
 sys.exit(app.exec_())

接下来实现各个控件的具体功能逻辑。

游戏开始时的初始界面如下。

当玩家点击“确定”提交答案且输入错误时，系统会弹出消息提示框。

答题环节结束后，系统将汇总并显示最终成绩。
