For faster response, could you please provide more details? For example, a screenshot or a code block.

The entire lecture on TF ROS2 is programming python script in a C++ package.
Can it bring some advantages by doing this?

[bayodesegun]

Yes. Among others, which are not possible in a Python package (ament_python),

1. You can also write C++ scripts if you need to.
2. You can create custom messages, services and actions.
3. If you are already used to ros1 way of doing things (cmake), you might flow better.
