I'm not entirely sure what you mean - I can't imagine a situation
where this would be useful. But you ought to be able to add hybrid
properties to a class after the class has been defined, and you can
use setattr if the name is stored in a variable. So I imagine
something like this ought to work:
def fget(self):
# code when property is accessed on instance
pass
def fset(self, value):
# code when property is assigned to
pass
def expr(cls):
# code when property is accessed on class
pass
prop = hybrid_property(fget, fset=fset, expr=expr)
# Add the hybrid property to a class under the name "propertyname"
setattr(SomeClass, 'propertyname', prop)
Hope that helps,
Simon
