"new" classes have a __new__ method. Classic classes generally do not. The type of a "new" class is types.TypeType The type of a classic class is a classobj The type of an instance of a "new" class is the name of the class The type of an instnce of a classic class is an instance
This is shown below: >>> class A(object): ... def __init__(self): ... pass ... >>> a= A() >>> class B: ... def __init__(self): ... pass ... >>> b= B() >>> type(A) <type 'type'> >>> type(a) <class '__main__.A'> >>> type(B) <type 'classobj'> >>> type(b) <type 'instance'> >>> I hope that this helps.
