How to get a list of all methods decorated with `@property`?

How to get a list of all methods of a class which have been decorated with the @property decorator?

Having the following example, the answer should get a list with only x and y included, but not z, since it hasn't been decorated with @property:

class C(object):
    def __init__(self):
        self._x = None
        self._y = None

    @property
    def x(self):
        """I'm the 'x' property."""
        return self._x

    @x.setter
    def x(self, value):
        self._x = value

    @x.deleter
    def x(self):
        del self._x

    @property
    def y(self):
        return self._y

    def z(self):
        pass

Use the following:

k = [name for name, value in vars(C).items() if isinstance(value, property)]

Now, print k

Prints: ['x', 'y']

Methods decorated by @property are instances of property:

>>> [name for name in dir(C) if isinstance(getattr(C, name), property)]
['x', 'y']
