Properties are meant to be used at the class scope. A property is a kind
of descriptor. See http://users.rcn.com/python/download/Descriptor.htm
for details of descriptors.

Please show us the code of what you are doing and describe what you are
trying to do. There are a lot many things one could do with a property
in __init__(). Mostly properties are just defined at the class scope.
And rarely would you access klass.x (where x is a property object),
mostly you would do instance.x.

Again, what exactly are you trying to do? The link above has some simple
examples of how to use properties.
