Using static and class methods - comparison

The time has come to compare the use of class and static methods:

1. a class method requires 'cls' as the first parameter and a static method does not;
2. a class method has the ability to access the state or methods of the class, and a static method does not;
3. a class method is decorated by '@classmethod' and a static method by '@staticmethod';
4. a class method can be used as an alternative way to create objects, and a static method is only a utility method.
