Import and use standard Python module from inside Python C extension

I have Python extension module written in C. I want to use in this C code one of the standard Python modules, for example os or shutil. How is best to do this?

Solution 
  • PyObject* os = PyImport_ImportModuleNoBlock("os");
if (os == NULL)
  return NULL;
someattr = PyObject_GetAttrString(os, "someattr");
Py_DECREF(os);

    If you import the module only once e.g., in init_yourmodule() function then use PyImport_ImportModule("os").
