Introduction

Exposes a mechanism for importing python modules.

Functions

import

object import(str name);
Effects: Imports the module named by name.
Returns: An instance of object which holds a reference to the imported module.

Examples

The following example demonstrates the use of import to access a function in python, and later call it from within C++. 
#include <iostream>
#include <string>

using namespace boost::python;

void print_python_version()
{ 
  // Load the sys module.
  object sys = import("sys");

  // Extract the python version.
  std::string version = extract<std::string>(sys.attr("version"));
  std::cout << version << std::endl;
}
