I am a beginner, and I am following the ros2 tutorial. I have a couple of questions about this tutorial: https://docs.ros.org/en/humble/Tutorials/Beginner-Client-Libraries/Writing-A-Simple-Py-Publisher-And-Subscriber.html

Q1: In line 1, we import rclpy, so why do we need to import Node separately in line 2?

Q2: In line 9, we write self as the argument of init function. Can we write anything else instead of self? For example, can we define the function as: def init(us):?

Q3: In line 10, we give the name minimal_publisher. Can I write anything else instead of minimal_publisher in line 27? Can I write in line 27: test_minimal_publisher = MinimalPublisher()

Q4: What will be the name of our node? Is it MinimalPublisher or minimum_publisher?

Thank you for your time.
