从python运行c ++代码 [英] running c++ code from python

问题描述

我想执行一个代码helloword.cpp，它从控制台接收一些参数来解析这些参数，然后在控制台中输出hello world。

I want to execute a code helloword.cpp which takes in some argument from console parses those arguments and then prints "hello world" in the console.

我想从一个python脚本中解析这些参数parsearguments.py

Now, I want to parse these arguments from a python scripts parsearguments.py

例如：

def parse_arguments:
  ...# some code
  return arguments

$ b b

现在，我如何在python和c ++之间进行通信。
我一直在看，看到cython，boost python是选项，但我很难找到正确的简单hello世界的例子。

Now, how do i communicate between python and c++. I have been reading and see that cython, boost python are the options but I have a hard time finding the right simple hello world example.

任何建议将不胜感激。
感谢

Any suggestions will be appreciated. Thanks

推荐答案

如何将使用Python生成的文本传递到C ++程序的标准输入中？基本上，你必须使用Python的 subprocess 模块启动C ++程序并将文本转储到其标准输出中。

How about passing whatever text you generate with Python into the standard input of your C++ program? Basically, you have to use Python's subprocess module to fire up the C++ program and dump the text into its standard output.

如果您的C ++程序需要在后台单独运行，您可以尝试其他形式的进程间通信，如unix域套接字。

In case that your C++ program is required to be running separately in the background, you could try another form of interprocess communication, like unix domain sockets.

使用boost： ：python也是一个选项，但它可能有点更难处理。

Using boost::python is also an option, but it might be a little more difficult to deal with.
