class Foo(object):
  def __init__(self, delegate):
    self._delegate = delegate

  def __getattr__(self, name):
    try:
      return getattr(self._delegate, name)
   except AttributeError:
      msg = "object '%s' has no attribute '%s' %
(self.__class__.__name__,

    name)
     raise AttributeError(msg)

class Boo(object):
   # your code here
   def run(self):
      print "This is a job for SuperBicycleRepairMan"

f = Boo(Foo())
f.run()
