I think there is a simpler answer to all this(not to take away from
the other ones here though which are all great). When writing
procedural code how would you like it if vars inside functions were
automatically global. Your code with be blowing chunks in no time.
Thats the reason for global

That was my point - I consider python's ordinary use of lexical
scoping to be a good thing, and I

I think you mean it's *Python* Object Oriented Programming. I am not
sure that every other OO language works like that.

Thank you, that makes sense to me.

problem is that you are confusing variables and attributes. In Python,
'anything.anyname' (note the dot) is the attribute 'anyname' of object
'anything'.
An easy mistake to make, given that scopes are just namespaces, and
