Hi,
can some one properly explain the differences between class types and
classic classes? ... Still face problems in identifying what is what.
I'm not sure I understand your question. Are you talking about the diff
between old-style and new-style classes, or the diff between classes and
metaclasses ?
"new" classes inherit from object. Classic classes do not.
"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.
