super-problem

[Max Khesin]

I was playing with super() and here is my session - the suggested usage of
super appears to produce an error. What am I missing? thanks -
max.


PythonWin 2.2.2 (#37, Oct 14 2002, 17:02:34) [MSC 32 bit (Intel)] on win32.
>>> print super.__doc__
super(type) -> unbound super object
super(type, obj) -> bound super object; requires isinstance(obj, type)
super(type, type2) -> bound super object; requires issubclass(type2, type)
Typical use to call a cooperative superclass method:
class C(B):
    def meth(self, arg):
        super(C, self).meth(arg)
>>> class B:
...  def meth(self, arg):
...   print ('B::meth, arg = %s'%arg)
...
>>> class C(B):
...  def meth(self, arg):
...   super(C, self).meth(arg)
...
>>> c = C()
>>> c.meth('Ho')
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "<interactive input>", line 3, in meth
TypeError: super() argument 1 must be type, not class
