As I said before, I think that the modules/classes in the standard library should have them.

You can help by submitting some patches (one module at a time please :-).

And docstrings are definitely doc, not code.

Agreed, but I don;'t understand why you said this.

This is true. While python doesn't require setting, I think this feature can be dangerous. It seems better to init the attr to None.

Agreed. The initialization to None can have a comment explaining what the subclass should do.

Ditto for methods: in an abstract base class, the methods should be defined (so the signature is known) but raise NotImplementedError.

In urllib2, there are 6 warnings about 2 different attributes.

How come PyChecker didn't find the other typo there?
