python继承和重写init方法--实例

class FooParent(object):      def __init__(self):          self.parent = 'I\'m the parent.'          print 'Parent'            def bar(self,message):          print message, 'from Parent'            class FooChild(FooParent):      def __init__(self):          FooParent.__init__(self)          print 'Child'                def bar(self,message):          FooParent.bar(self,message)          print 'Child bar function.'          print self.parent            if __name__=='__main__':      fooChild = FooChild()      fooChild.bar('HelloWorld')
