class arguements

[buran]

in python3 there is no difference. object is base class for all classes and it's not necessary to explicitly inherit from object.

>>> class Foo:
...     pass
... 
>>> type(Foo)
<class 'type'>
>>> class Bar(object):
...     pass
... 
>>> type(Bar)
<class 'type'>

In python2 there are old-style (or classic) class and new-style class. For compatibility reasons, classes are still old-style by default. To be new-style class, it had to inherit from object explicitly.

>>> class Foo:
...     pass
... 
>>> type(Foo)
<type 'classobj'>
>>> class Bar(object):
...     pass
... 
>>> type(Bar)
<type 'type'>

New-style and classic classes

where the class is given an arguement,

in terms of terminology object is not argument, it's a parent class from which your class inherits. Of course your class can inherits from other custom class, e.g.

class Vehicle:
    pass

class Car(Vehicle):
    pass

But basics of inheritance is explained in the link I shared in the other thread already.
