Is @classmethod just like a bookmark to tell the people to work on the code that it belongs to the class method above?

A decorator is a design pattern in Python that allows a user to add new functionality to an existing object without modifying its structure. ... Decorators are usually called before the definition of a function you want to decorate.
From here:
https://www.datacamp.com/community/tutorials/decorators-python
Think of a decorator as a function wrapper that boosts an existing function's capabilities
For example, in this video:

Ridley (Sigourney Weaver) is like a function. Her "loader" suit is like a decorator, making her effectively super-human.
These should help you understand Python decorators better:
