looking for a descriptor example (newbie)

[Karthik Gurumurthy]

hi all,

I wanted to understand descriptors properly.

http://www.amk.ca/python/2.2/index.html#SECTION000320000000000000000

please take a look @ this wonderful article.
Can someone provide me a simple implementation of
eiffelmethod using descriptors.

It says descriptors live inside the classes. Is it a static member of the
classes?
how do you write one?

thanks,
karthik.
