Python 3 has only new-style classes that are declared as class A:, class A(object): or class A(B):. For classic-style classes, a comparison operation always calls the method of the first operand, while for new-style classes, it always calls the method of the subclass operand, regardless of the order of the operands .Note that we don't use a string representation of the name of the class. In Python, you can just use the class itself. Share. Improve this answer. Follow answered Aug 10, 2010 at 19:53.
