Strange sorting error message

[Dustan]

I'm hiding some of the details here, because I don't want to say what
I'm actually doing.

I have a special-purpose class with a __cmp__ method all set up and
ready to go for sorting. Then I have a special class that is based on
the builtin type list (though I didn't actually inherit list; I
probably should). When I create an instance with 2 or more items, and
attempt to sort it, I get this strange error message:

>>myList.sort()

Traceback (most recent call last):
File "<console>", line 1, in <module>
File "[listModulePath]", line 239, in sort
self.listOfObjects.sort()
TypeError: an integer is required

The sort method's code is exactly what you see; it's a one-line method.

The only thing I can think of is the __cmp__ method is returning
something other than an integer, which it's not.

Does stuffing the objects in a standard list and sorting them work? How
does the __cmp__-method look like?

Whoops, I had created the variable returnValue in __cmp__, but
forgotten to return it. Now it works.

That was a dumb mistake; sorry for the trouble.

That's great, seeing as I already figured out the answer, as I have
already posted in a reply.

Are you saying I broke one of these rules?

Or are you just being plain rude?
A lack of a response from you implies the latter...

I had a good laugh at it.

It was a joke, based on you hiding what you are doing, he decided
to hide the solution to your problem. Get it?

Ah, now I get it... Well, not really. I'm not outgoing, so it's hard
for me to spot a joke when I see one.

Even when it smacks you in the face, apparently. Anyway, I'm sorry if
you thought I was getting at you in any way. Just trying to amuse the
group ...

What if it was for a proprietary software of some kind?

It wasn't sufficiently clear, hence the mild ribbing.
