>>> print property.__doc__
property(fget=None, fset=None, fdel=None, doc=None) -> property
attribute

fget is a function to be used for getting an attribute value, and
likewise
fset is a function for setting, and fdel a function for del'ing, an
attribute.  Typical use is to define a managed attribute x:
class C(object):
def getx(self): return self.__x
def setx(self, value): self.__x = value
def delx(self): del self.__x
x = property(getx, setx, delx, "I'm the 'x' property.")

I started with the "How-To Guide for Descriptors" by Raymond Hettinger
http://users.rcn.com/python/download/Descriptor.htm

It is one of several docs on the "New-style Classes" page at python.org
