Hi there,
I am somewhat confused by the following :
class C(object): def getx(self): return self.__x def setx(self, value): self.__x = "extended" + value def delx(self): del self.__x x = property(getx, setx, delx, "I'm the 'x' property.")
So far so good :-) But what to do with this now
c = C c
<class '__main__.C'>
dir (c)
['__class__', '__delattr__', '__dict__', '__doc__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__str__', '__weakref__', 'delx', 'getx', 'setx', 'x']
c.x
<property object at 0x401edbbc>
?????? What can I do with this "property object" now.
Well, if you actually want your getx/setx/delx to be called, then you need an *instance* of class C:
py> c = C() py> c.x Traceback (most recent call last): File "<interactive input>", line 1, in ? File "<interactive input>", line 2, in getx AttributeError: 'C' object has no attribute '_C__x' py> c.x = "42" py> c.x 'extended42' py> del c.x py> c.x Traceback (most recent call last): File "<interactive input>", line 1, in ? File "<interactive input>", line 2, in getx AttributeError: 'C' object has no attribute '_C__x'
Note that I used 'c = C()' instead of 'c = C' as in your code.
