What are the differences between the @classmethod and @staticmethod decorators in Python?

@classmethod takes the class reference (cls) as the first argument, automatically passed by the interpreter during the call. It is used for creating factory methods or methods that work with class attributes.

@staticmethod does not implicitly take the class or instance as the first argument. Essentially, it is a regular function defined within a class for logical grouping. It does not have access to the instance or class state.

class MyClass:
    count = 0

    def __init__(self, value):
        self.value = value
        MyClass.count += 1

    @classmethod
    def create_from_value(cls, value):
        # Class method, has access to the class MyClass via cls
        return cls(value)

    @staticmethod
    def display_info(item):
        # Static method, has no access to class or instance
        print(f"Object value: {item.value}")

# Usage
obj1 = MyClass(10)
obj2 = MyClass.create_from_value(20) # Call via class method

MyClass.display_info(obj1) # Call static method
# MyClass.display_info(MyClass) # Does not work if the method expects an instance

Characteristic	@classmethod	@staticmethod
First argument	Reference to the class (cls)	None
Access to state	Class	Neither instance nor class
Main purpose	Factory methods, working with class attributes	Logical grouping of functions within a class
Call	Via instance or class	Via instance or class
