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.

Colin,
I don't personaly need much help with this !-) In fact, your answer is
almost the same as the one I was going to post - before I re-read the
OP's question. And I'm still not sure that what the OP is looking for.

Dear Colin,
Forgive me for this late reply. Your explanation was of great help to
me.
Thank you very much. It was crystal clear.

Is there a builtin way of making making another instance of your own

Currently i'm doing this:

I'm talk from the point of view of descriptors. Consider
a.x = lambda self:None # simple function
When a.x is later got, what criterion is used to see if a class (and so the
func would have __get__(None, a) called on it)? Pre-metaclasses, one might
assume it was

hi,
I am kind of confused aobut interfaces and abstract classes.
In short as I understand it, an interface is like a contract between
the class and the interface, so that certain funtions must be
implemented. So if you have a class which inherits base class that
inherts an interface, then your classes will have a standard. I suppose
you can also check for interface at run time say when dll is loaded and
see if it implememts whats...

Is there a way to persist a class definition (not a class instance, the actual class) so it can be restored later? A naive approach using pickle doesn't work:
>>> import pickle
>>> class Foo(object):
... def show(self):
... print "I'm a Foo"
...
>>> p = pickle.dumps(Foo)
>>> p
'c__main__\nFoo\np0\n.'

Hi everybody,
I have the following problem :
B class need A::MyEnum type and A class need B::MyEnum type.
In both case, the class type is incomplete so it is obvious that the
::MyEnum can not be found in the class definition (the compiler
complains)
My problem is the MyEnum types have to be defined inside the class

Hello,
Can someone explain to me the difference between a type and a class?
After reading http://www.cafepy.com/article/python_types_and_objects/
it seems to me that classes and types are actually the same thing:
- both are instances of a metaclass, and the same metaclass ('type')
can instantiate both classes and types.
- both can be instantiated and yield an "ordinary" object
- I can even inherit from a type and get a class

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
