I did no such thing, I likened classes to templates and as far as I can
tell they are _like_ templates albeit dynamic ones.

I see that.

Yeah no s*** that's trickier! Still haven't quite wrapped my head round
it yet even after reading the 'language definitions carefully' (well
http://www.python.org/doc/2.5.2/tut/node11.html at least) although I am
a bit clearer about the difference between class attributes and instance
variables. Time to go rewrite some crappy old code!

One of the things I love about Python is how it allows you to just
breeze by on intuition alone! It makes it immediately (and
incrementally) useful in the real world and I've been ableto built up a
great little library of scripts as I've learned. Having said that I
appreciate bigger projects require a deeper understanding which is why I
hang out here and occasionally ask dumb questions. Thankfully from time
to time clever bods like you will spot and point out the gaps in my
knowledge.
