@Jean. Thanks for the reply. But this is not what I wanted. The import hook already restricts socket imports in applications. But I want them in sdk package (alone) which is being imported in the application. I don't want applications to directly use the socket module. That means I want to make some exceptions for sdk in import hooks. -- http://mail.python.org/mailman/listinfo/python-list
