They are two different instances of the same class. The sayHello functions are bound methods.
That is, if you have a class instance:
p = Person()
and you lookup an attribute on it:
p.sayHello
then Python first looks at the actual attributes of the instance, and if it does not find the attribute there, it looks at the class. If it finds a class method of that name, it turns it into a bound method, bound to this instance. That is the magic that results in the object instance being passed as the first argument (self) to sayHello.
So Person().sayHello is Person().sayHello creates two instances, creates two different bound methods based on the same method defined on the class, and thus is returns False because they're different methods.
