Failed to get question list, you can ticket an issue here. I know I could achieve that with XML in ROS2 too, but I was curious to make it in python since it seems to be a more "ROSish" way to do it, nowadays. If the entity e is wrapping it, the following statements will be true: By default, the value of the attribute is returned as a string. : Union[List[int], int]. Sign in Setup your ROS2 Python package Before you can create a ROS2 Python package, make sure you have : correctly installed ROS2, setup your environment (add source /opt/ros/ROS_VERSION/setup.bash in your .bashrc - don't forget to replace "ROS_VERSION"), and created a ROS2 workspace ( $ mkdir -p ~/ros2_ws/src && cd ros2_ws/ && colcon build ). - lists: Can be uniform like List[int], or non-uniform like List[Union[str, int]], List (same as list).

Hi, I migrate some packages to ROS2 (humble) and I don't find an equivalent of the if and unless arguments I had in ROS1 (noetic) XML launch files for python ROS2 launchers.
