Is it possible to implement a function that works without creating an instance of a class?

Yes, in Python, you can implement a function that works without creating an instance of a class by using the @staticmethod decorator.

Example:

class MyClass:
    @staticmethod
    def greet(name):
        return f"Hello, {name}!"

# Call without creating an instance
print(MyClass.greet("World"))  # Outputs: Hello, World!

Static methods do not take the self parameter and can be called directly through the class.
