Give me a Python code to print "Visible changed:", visible given the following:
Complete the below
def WithEvents(disp, user_event_class):

    ''''Similar to DispatchWithEvents - except that the returned
    object is *not* also usable as the original Dispatch object - that is
    the returned object is not dispatchable.
    The difference is best summarised by example.
    >>> class IEEvents:
    ...    def OnVisible(self, visible):
    ...       print "Visible changed:", visible
    >>> ie = Dispatch("InternetExplorer.Application")
    >>> ie_events = WithEvents(ie, IEEvents)
    >>> ie.Visible = 1
    Visible changed: 1
    Compare with the code sample for DispatchWithEvents, where you get a
    single object that is both the interface and the event handler.  Note that
    the event handler instance will *not* be able to use \'self.\' to refer to
    IE\'s methods and properties.
    This is mainly useful where using DispatchWithEvents causes
    circular reference problems that the simple proxy doesn\'t deal with'
