You don't need an apply method for that, property already takes four
arguments, so you can write:
def factory():
def fget(self): pass
def fset(self, value): pass
def fdel(self): pass
return (fget, fset, fdel, "doc")
attr = property(*factory())
# optional: del factory
but frankly, having to write the property getters and setters as nested
functions is (in my opinion) uglier looking and more annoying than the
usual property chaining version.
So if you want to use this with decorator notation, you need a one-line
helper:
def myproperty(func):
return property(*func())
and change the name of "factory" to "attr".
