// PyObject* PyImport_ImportModule(const char *name) // Return value: New reference. // This is a simplified interface to PyImport_ImportModuleEx() below, leaving the globals and locals arguments set to NULL and level set to 0. When the name argument contains a dot (when it specifies a submodule of a package), the fromlist argument is set to the list ['*'] so that the return value is the named module rather than the top-level package containing it as would otherwise be the case. (Unfortunately, this has an additional side effect when name in fact specifies a subpackage instead of a submodule: the submodules specified in the package’s __all__ variable are loaded.) Return a new reference to the imported module, or NULL with an exception set on failure. Before Python 2.4, the module may still be created in the failure case — examine sys.modules to find out. Starting with Python 2.4, a failing import of a module no longer leaves the module in sys.modules. // // Changed in version 2.4: Failing imports remove incomplete module objects. // // Changed in version 2.6: Always uses absolute imports. func PyImport_ImportModule(name string) *PyObject { c_name := C.CString(name) defer C.free(unsafe.Pointer(c_name)) return togo(C.PyImport_ImportModule(c_name)) }
