[Tutor] Defining a new class

[VanL]

Hello,

I am just getting started with Python so I thought I would implement
a lot of the classical data structures in Python so as to get a feel
for it.  I am running into a few difficulties, tho.  Here is my
first Python class:

class LinkedList:

    def __init__(self, name, object=None):
        self.label = name
        if object: self.link = object
        else: self.link = None

    def next(self):
        if self.link: return link
        else: return None

    def label(self):
        return self.label

    def link(self, object):
        self.link = object

    def unlink(self):
        self.link = None

    def rename(self, name):
        self.label = name


Some things work as expected; I can declare an object of type
LinkedList.  I get some strange results overall, tho.  For example:

>>> from LinkedList import *
>>> dir(LinkedList)
['__doc__', '__init__', '__module__', 'label', 'link', 'next',
'rename', 'unlink']

So far so good.

>>> Me = LinkedList('MyName')
>>> MyFriend = LinkedList('HisName', Me)
>>> print Me.label()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: call of non-function (type string)

I'm a little confused about that.  I'm calling a function, aren't I?

Still, after a little checking, I found

>>> print Me.label
MyName

Still, I am confused.  Moreover, the next function isn't working as
I expected. I thought that
>>> print Me.next

should return

None

Instead, it returns

<method LinkedList.next of LinkedList instance at 0082A45C>

Similarly,
>>> print (MyFriend.next).label

should return

MyName

Instead, it returns

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: label

Also,
>>> print MyFriend.next
<method LinkedList.next of LinkedList instance at 0082D65C>

seems to show that I am not even getting back to my original node
"Me".

Could anyone enlighten me?

Thanks very much,

Van
