Hello,
I want to set up descriptors at runtine, but it isn't working the way
i would expect. Does anybody know if this is possible? Here is an
example:
class Descriptor(object):
def __init__(self, name) :
self.val=0
self.name = name
def __get__(self, obj, objtype):
print 'Retrieving', self.name
return self.val
def __set__(self, obj, val):
print 'Updating' , self.name
self.val = val
class TestDesc (object):
x=Descriptor ("x")
def __init__ (self):
self.y=Descriptor("y")
And Usage:
>>> test=TestDesc()
>>> test.x=0
Updating x
>>> test.x=4
Updating x
>>> test.x
Retrieving x
4
>>> test.y
<descriptor.Descriptor object at 0x00B3A5F0>
When i access y, it appears to be a regular object and not a
descriptor type object like x. Is there a way to make y work the same
as x but setting it up during object creation?
thanks,
brian
