Yes. It's called Object Oriented Programming.

For a language as well structured as Python, this seems somewhat
sloppy, and inconsistant. Or is there some good reason for this?
Here is what I mean:
def a():
x = 99
print x
def b():
print x
a()
b() # raises an exception because x is not defined.
However in the methods are within
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 declar

Not really, self is a formal parameter to the function. It would be
a strange language where a function'

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

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.

I suppose you could do this:
class className():
varname = "whatever"
def fname(self, varname):

Not really. Hopefully this commentary will show you why.

An easy mistake to make, given that scopes are just namespaces, and
