这个博客介绍了一个使用Python QT构建的乘法程序。程序包含三个字段：两个只读的随机数字段和一个用于用户输入结果的字段。当用户输入的结果与随机数相等时，显示'Right Label'，否则显示'Wrong Label'。博主希望通过点击'再次播放'按钮替换退出按钮，以实现重新生成随机数并清空结果的功能。

我有一个简单的python QT乘法程序 . 有3个字段，第一个随机数(只读)，第二个随机数(只读)和第三行编辑，供用户输入结果 . 如果first * second = result，则显示Right Label，否则显示Wrong Label . 我想用再次播放按钮替换退出按钮，所以当用户按下它时，重新生成随机数并清除所有结果标签，用户再试一次 .
