What is a Python code to print \'Task %s is %d%% complete given the following:
Complete the below
def WaitForTask(task, raiseOnError=True, si=None, pc=None, onProgressUpdate=None):

    ''''Wait for task to complete.
    @type  raiseOnError      : bool
    @param raiseOnError      : Any exception thrown is thrown up to the caller
    if raiseOnError is set to true.
    @type  si                : ManagedObjectReference to a ServiceInstance.
    @param si                : ServiceInstance to use. If None, use the
    information from the task.
    @type  pc                : ManagedObjectReference to a PropertyCollector.
    @param pc                : Property collector to use. If None, get it from
    the ServiceInstance.
    @type  onProgressUpdate  : callable
    @param onProgressUpdate  : Callable to call with task progress updates.
    For example::
    def OnTaskProgressUpdate(task, percentDone):
    print \'Task %s is %d%% complete.\' % (task, percentDone)'
    '''
