There are six equality/relationship methods. They represent what happens if an object is compared using any of the following symbols:

Function	Corresponding symbol and meaning
object.__lt__(self, other)	<, smaller
object.__le__(self, other)	<=, smaller or equal
object.__eq__(self, other)	==, equal
object.__ne__(self, other)	!=, not equal
object.__gt__(self, other)	>, larger
object.__ge__(self, other)	>=, larger or equal

class Person:    '''person entity'''    def __init__(self, name, surname, age):        self.name = name self.surname = surname ...
