#53543 — problem of double import in python

Dear all,

I remember to avoiding to confusing compiler for header, use 
/////////////////
// in my include file
#define MYHEADER_H
// and in others code use:
#ifndef MYHEADER_H
#include blahblah
/////////////////////////

Unfortunately, i prevent to same error, double import to python, but i
don't know how to solve, Even i don't know policy of python programmers.

You'll make me happy if explain me...

Yours,
Mohsen

You don't need to do anything, Python takes care of this for you.

During execution, a module is only loaded the first time it is imported. 
Every following import will notice that it has already been loaded and 
return a reference to the module instead.
