How do I use the @classmethod decorator in Python?
Article Introduction：@classmethod is used in Python to define a class method that receives a class (cls) as the first parameter, not an instance (self), allowing it to access or modify class-level data or create instances. It is suitable for alternative constructors, handling class-level states, and implementing factory patterns. Unlike @staticmethod, the latter does not receive class or instance parameters. For example, you can use @classmethod to implement different object creation methods, such as initializing Person instances with full names. Additionally, @classmethod performs well in inheritance and will correctly pass its own class when called. When using it, make sure that the test class and instance call behavior are consistent and avoid overuse.
