I have a few questions about this:

(1) Looking over the documentation, I have noticed that in
python 2.2, you have to subclass every class. If there is no
super class to base your new class, then you have to use the
default "(object)". Am I correct?

(2) If I am right in number (1), then I really should get python
2.2. Otherwise, I will be writing code that will eventually be
incompatible.

(3) Since my version of python (2.1) is working so well, I am
just a bit reluctant to install a new version. I am running
Mandrake 8.1 on a pentium 1 box. Has anyone out there had any
problems with installation?

Thanks!
