# @classmethod means: when this method is called, we pass the class as the first argument instead of 
# the instance of that class (as we normally do with methods). 
# This means you can use the class and its properties inside that method rather than a particular instance.

# @staticmethod means: when this method is called, we don't pass an instance of the class to it
# (as we normally do with methods). 
# This means you can put a function inside a class but you can't access the instance of that class 
# (this is useful when your method does not use the instance)
