>>> c = C() >>> type(c).x.__doc__ "I'm the 'x' property." But usually you'll see it as part of the help on c: >>> help(c) Help on C in module __main__ object: class C(__builtin__.object) [...] | Data descriptors defined here: [...] | x | I'm the 'x' property. -- https://mail.python.org/mailman/listinfo/python-list
