No, currently this is not possible. There were some attempts for python bindings for controllers afair, maybe @olivier-stasse can give an update on this topic.
If you don't have hard realtime requiremtents, you can use a topic based system with existing python hardware drivers.
Dear @zouzhe1 , There is no solution which fits all the problems.
The ros2_controllers are already covering a large part of real life robotics problem.
But if you are designing your own controller and it is quite complex, I would strongly advice to decouple the mathematics from the encapsulation. You can view the ros2_controller interface as a standard interface to encapsulate controllers.
If you are quite good at python you can try: https://github.com/ICube-Robotics/pytroller generating a ros2_controller from python.
For complex controller, such as inverse dynamics on humanoid robot, and quick prototyping it is usually recommended to check the math with python following examples such as: https://github.com/stack-of-tasks/tsid/tree/master/exercizes if you want to do Task Space Inverse Dynamics.
Then you can deploy it in a custom ros2_controller.
We wrote some python bindings to ros2_control, but they need more work.
Can I use Python to fully write the Ros2 control package?
Because I am not familiar with CPP, and I am used to using Python libraries such as can, canopen, and so on.
And my Python program for controlling hardware has already been written
