The current RTAI base implementation of HAL runs real-time HAL components as loadable kernel modules. Python (or any other interpreted language) simply does not work at all in that environment. Non-realtime modules are normal Linux processes. I believe that there is a library to allow Python to interact with HAL in that environment.
