我得到一些我无法弄清楚的错误.任何线索我的示例代码有什么问题？

class B:
    def meth(self, arg):
        print arg

class C(B):
    def meth(self, arg):
        super(C, self).meth(arg)

print C().meth(1)

我从"超级"内置方法的帮助下得到了示例测试代码."C"级是

这是错误:

Traceback (most recent call last):
  File "./test.py", line 10, in ?
    print C().meth(1)
  File "./test.py", line 8, in meth
    super(C, self).meth(arg)
TypeError: super() argument 1 must be type, not classobj

仅供参考,这是来自python本身的帮助(超级):

Help on class super in module __builtin__:

class super(object)
 |  super(type) -> unbound super object
 |  super(type, obj) -> bound super object; requires isinstance(obj, type)
 |  super(type, type2) -> bound …

在Python中,请考虑我有以下代码:

>>> class SuperClass(object):
    def __init__(self, x):
        self.x = x

>>> class SubClass(SuperClass):
    def __init__(self, y):
        self.y = y
        # how do I initialize the SuperClass __init__ here?

如何SuperClass __init__在子类中初始化？我正在关注Python教程,但它没有涵盖这一点.当我在Google上搜索时,我找到了不止一种方法.处理这个问题的标准方法是什么？
