使用boost.python从C ++将变量导出到python中

Question

I have, for example, a varibale in c++:

const float Pi = 3.1415926535898f;

What is the best way to export it into python-module using boost.python?

I want to access it as variable in global scope.

Answer 1

似乎可以使用以下方式轻松完成：

boost::python::scope().attr("Pi") = Pi; 

Answer 2

PyModule_AddObject，如果你想将它注入从python文件导入的模块。
