Skating on thin ice eh.Read something on metaclasses.
class Meta(type):
def __getattribute__(klass,attr):
value=type.__getattribute__(klass,attr)
print attr,'==',value
return value

class Foo(object):
__metaclass__=Meta
a=2

Foo.a

Read something on metaclasses.

Depending on what you want to do, it might be better to use properties
instead:

class Meta(type):
x = property(lambda klass: 'Called for '+str(klass))

class Foo(object):
__metaclass__=Meta

print Foo.x

Also worth noting that you can inline the metaclass if you don't need it
anywhere else, e.g.:

class Foo(object):
class __metaclass__(type):
x = property(lambda klass: 'Called for '+str(klass))
