Class declaration in python with or without object in parameter

Question

What is difference between these two type of class declarations?

class ClassName():

class ClassName(object):

What does this object parameter does?

In Python 3, there is no difference, since all classes implicitly inherit from object — juanpa.arrivillaga

In Python 3 you don't even need the brackets, just use class Foo:. — DocDriven

In Python 2 from 2.1, there are two kinds of classes, new-style and classic. Deriving from object in Python 2, from 2.1 on, will create a new-style class. In Python 3, there's only one kind, and so both forms are the same.
