Python Embedded C ++ (2)-import module

First, I have to mention a very good website: http://www.codase.com/index.html

This is what I found when searching for Embedded functions. There are a lot of small instance code in it, so it is really time to see (haha)

 

The preceding describes the configurations needed for embedding (see the http://blog.csdn.net/xiadasong007/archive/2009/09/02/4511841.aspx), this time mainly to illustrate how to call the basic methods of functions in the python module in C/C ++.

Prerequisites:

1: pyobject * obj is a bit like a handle in the SDK.

2: Call the python module process: first load the module. After loading, you can directly access it (⊙ o ⊙ ~! Very simple ~

 

Okay. Let's see the code:

# Include "Python/python. H"

# Include <iostream>
Using namespace STD;

 

Int main (INT argc, char ** argv)
{
Pyobject * pmodule, * pfunc, * pvalue;

Py_initialize ();
////////////////

Pmodule = pyimport_importmodule ("mat"); // mat is a small module (mat. py) Written in Python by myself. For details, see the appendix below.

Pvalue = pyobject_callmethod (pmodule, "add", "II",); // directly access the function add (A, B) in the module through the module obtained above)

// Note that the "II" here is actually equivalent to the "% d" feature in C. Please refer to the documentation
Cout <pylong_aslong (pvalue) <Endl; // convert the obtained pvalue value to the long type in C.

 

Pfunc = pyobject_getattrstring (pmodule, "add"); // you can use this function to obtain the function object.
Pvalue = pyobject_callfunction (pfunc, "II",); // execute a function through a function object
Cout <pylong_aslong (pvalue) <Endl;
////////////////
Py_finalize ();
Return 0;
}

 

// Appendix: mat. py

/*

Def add (A, B ):

Return A + B
