[Tutor] Slightly OT: public/private class members

Sorry, what does that mean exactly? Do you mean why doesn't 
python insist in declaring variables before you use them? 
I think thats what VB does with strict? Or is it a Perl 
thing?... Anyway what do you mean? Why would it help?

> and why are all variables global in scope. 

They aren't. Whatever gave you that idea? 
Python has 3 levels of scope:

builtins, module or file(what the docs call global) and 
local(inside a function). Also classes define a kind of 
local scope too.

See the namespaces topic in my tutor for more info.
