c++代码和py代码如何混合编程使用

混合编程使用C++和Python可以通过以下几种方式实现：

1. 使用Python的C API：Python提供了C API，可以在C++中使用Python解释器，从而在C++代码中调用Python函数或模块。

2. 使用Boost.Python：Boost.Python是一个C++库，它提供了一组工具和库，可以很方便地将C++类和函数暴露给Python，或者在Python中调用C++函数和类。

3. 使用SWIG：SWIG是一个可以将C++和其他语言（包括Python）混合的工具，它可以自动生成语言之间的接口代码。

4. 使用Cython：Cython是一个将Python代码转换为C代码的工具，它可以使用C++扩展来编写高效的Python代码，同时也可以在Python代码中调用C++函数。

需要根据具体的情况选择适合的方法，例如需要考虑代码的可维护性、性能等方面的因素。

Qt基于C++，不要py代码

好的，非常抱歉之前理解有误。

Qt是一个基于C++的跨平台应用程序开发框架，它提供了一系列的类库和工具来简化GUI程序的开发。Qt支持多种操作系统，包括Windows、macOS、Linux、Android、iOS等等。

下面是一个简单的Qt程序示例：

#include <QApplication>
#include <QLabel>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel("Hello Qt!");
    label->show();
    return app.exec();
}

这个程序创建了一个名为“Hello Qt!”的标签，并显示在窗口中。调用`app.exec()`方法开始Qt的事件循环，等待用户的输入操作。

这只是一个简单的示例，Qt还提供了很多其他的功能，如多线程、网络编程、数据库连接等等。如果您对Qt感兴趣，可以去Qt官网上查看更多的文档和示例。
