Hi, I am at the end of ROS Topics - part2, all right up to here. I have not experience about python language. I am trying to solve the Quiz: I do not know what code to write to extract the middle data LaserScan/ranges. I believe to understand that the topics_quiz_node works as a controller, but:

1. does the topics_quiz_node is both a publisher and a subscriber node in which also runs the controller code (only one file: control_robot.py)? (I thinks so) or,
2. there are three file.py? (publisher.py, subscriber.py and control_robot.py)
thanks
