本文介绍了如何利用Boost库的Boost.Python模块，特别是converter::as_to_python_function函数，将自定义的C++类如Person转换为Python对象。文中通过创建Person类并实现转换函数，展示了将C++对象转成Python Dictionary的过程，实现了C++与Python的互操作性。

boost::python::converter::as_to_python_function函数的使用

在C++编程中，Boost库是一个非常有用的工具箱，其中，Boost.Python库可以帮助开发者在C++代码中轻松嵌入Python解释器，从而实现C++和Python的互操作性。本文将介绍使用Boost.Python库中的converter::as_to_python_function函数将一个自定义的C++对象转换为Python中的对象，并提供相应的测试程序。

首先，我们需要定义一个自定义的C++对象，在本例中，我们定义一个名为Person的类，它有两个私有成员变量：姓名和年龄。

#include <string>

class Person {

其中，boost::python::converter::arg_to_python是一个重要的功能，它用于将C++类型转换为Python对象。接下来，我们将创建一个简单的C++类，然后使用boost::python::converter::arg_to_python将其导出到Python。接下来，我们将创建一个简单的C++类，然后使用boost::python::converter::arg_to_python将其导出到Python。然后，我们在Python中使用导出的类创建了一个对象，并调用了。

其中，boost::python::to_python_converter是一个非常有用的函数，它允许我们自定义将C++类型转换为Python类型的方式。在本文中，我们将介绍一个使用boost::python::to_python_converter的测试程序。通过这个简单的示例，我们展示了如何使用boost::python::to_python_converter函数来自定义类型转换器，以便在C++和Python之间进行交互。首先，我们定义一个简单的C++类，叫做。接下来，我们将编写一个转换器，将。
python中convert函数怎么用_PIL包中Image模块的convert()函数的具体使用

将彩色图片转换成黑白图片是自己拿到的第一个小任务。在全文开始之前给自己科普一个公式：RGB到灰度图转换公式：Y' = 0.299 R + 0.587 G + 0.114 B网上有诸多版本的转换公式，但是系数大同小异。接下来是正文。由于几乎可以说是零基础= =所以只好赶紧依靠pip install pillow把PIL装好。。。convert()函数，用于不同模式图像之间的转换。PIL中有九种不同...

作者：fasiondog万事开头难！前段日子因为性能问题升级了机器，程序语言也从python转到了C++，不过因为数据分析的问题，还是交互式的环境用着方便，于是埋头又将编好的C++库切回python，不过这一回用的是Boost.Python，刚开始编译总是有问题，查看文档才发现Boost.Python中的构建说明帮助不够完全，如果没仔细学习Boost.Build的话，要按自己的方式编译的话还是很麻...
Python调用C++代码（含OpenCV cv::Mat转换 传输数据）

简介 Python因为编写简单、易用而被广泛使用，但是其效率比较低下。尤其是在计算机视觉、图像处理领域，C++调用GPU，相对于Python可能是10倍以上的提速。一些开源的算法通常是使用C++来实现。经常会有需求需要快速用Python实现一个项目，然后其中要调用一段C++代码。 本方法使用了一个开源库，pyboostcvconverter，这个C++库被编译后，会生成.so，在.so路径下，就可...

boost python的使用

之前的文章 Python扩展模块实现中，介绍了如何使用c++编写python的扩展模块，现在我们有了新的选择，因为Boost提供了Python库，我们可以很容易的使用它来在C++应用程序中嵌入Python（目前有些功能可能还需要调用Python API）；也可以使用它来扩展Python，在这方面的功能更强大。 1. Boost Python库的编译 boost中的组件，大部分都不需

来源：http://blog.youkuaiyun.com/KongDong 作者：fasiondog 万事开头难！前段日子因为性能问题升级了机器，程序语言也从python转到了C++，不过因为数据分析的问题，还是交互式的环境用着方便，于是埋头又将编好的C++库切回python，不过这一回用的是Boost.Python，刚开始编译总是有问题，查看文档才发现Boost.Python中的构建...
使用boost::python::to_python_converter进行类型转换的示例
HackQuestR的博客

在convert()函数中，我们创建一个Python对象pyObj，该对象的值为obj.getValue()，然后使用py::incref()函数递增一次PyObject的引用计数，并返回该PyObject指针。最后，程序打印了从Python环境中读取的值。最后，在BOOST_PYTHON_MODULE宏内部，我们使用py::class_来将MyClass注册为Python类型，并使用to_python_converter()函数将MyConverter注册为MyClass类型的转换器。

把我在实际过程中遇到的问题，总结一下，请先阅读：python教程，python FAQ1.如果封装的c++类没有拷贝构造函数怎么办？定义class的时候，加入模板参数boost::noncopyable，同时指定no_init class_("ExpandEmitter",no_init);拷贝构造的目的是，c++对象实例传递给python时，可以通过拷贝构造重新构造一个pytho
C++传递参数给Python

1.总结 C++传递参数给Python，需要转换成PyObject *类型。比如，C++的 int 是一个整数，该值占用 8bytes(64位)的存储空间，而一个 python 的 int 实际是一个 PyObject* 指向 24bytes。前 8个bytes是整数，代表引用次数；中间 8bytes是指向 int 类型定义的指针，最后 8bytes是才是这个 int 的值。所以 C++ 和 Python 之间参数互相传递都需要 Python提供的 api。 2.案例 PyObject* arg1

c++和python的互相调用

我们有一个python写的斐波那契数列，但是运行速度太慢，因为Cython中有C语言的特性，所以我们可以使用Cython语言重写斐波那契数列，然后编译为动态链接库，然后在python代码中使用。这是最暴力的一种方法，我们知道，python这个语言也有C的API，所以我们可以直接在C语言代码中使用这些API来调用python模块，下面是一个简单的示例。上面我们已经说过，Cython是python的超集，所以如果我们有一个python脚本或者模块，想要在C语言环境中调用它，那么可以使用cython对这个。
