    self.name = name
  def printest(self):
    print "base class: ", self.name
class subclass1(base):
  """sub class 1"""
  def printest(self):
    print "sub class 1: ", self.name
class subclass2(base):
  """sub class 2"""
  def printest(self):
    print "sub class 2: ", self.name
class subclass3(base):
  """sub class 3"""
  pass
def testFunc(o):
  o.printest()
if __name__ == "__main__":
  testFunc(subclass1("1"))
  testFunc(subclass2("2"))
  testFunc(subclass3("3"))
