You can dynamically add properties to a class
The OP was asking for *per instance* properties...
just before returning
the
instance using __new__():
class AClass(object):
def __new__(cls):
setattr(cls,"propName", property(fget = ...,
fset = ...,
fdel = ...,
doc = ...) )
obj = super(AClass, cls).__new__(cls)
return obj
Very bad idea IMHO. __new__ is called on each instanciation, which means
the above code will uselessly modify the class each time you create an
instance of it, overwriting the same properties again and again and
again. If what you want is to automagically add properties (or whatever
type of attributes) to a class and/or it's subclass, you'd be better
using a custom metaclass.
