Note that in python we don't normally bother with getA/setA normally,
just use self.A, eg
class Stuff(object):
def __init__(self):
self.A = None
self.B = None
def main(self):
print self.A
print self.B

Note that while you *can* do direct access to the implementation attribute
(here, '_A' for property 'A'), you don't *need* to so (and usually shouldn't
- unless you have a very compelling reason).
Interesting. Why

Check by yourself:
import inspect
inspect.isfunction(property)
False
Using this, every single builtin function returns False. That's a
pretty limited definition to be being pedantic over, especially when
they are in the

Use the global statement.
http://docs.python.org/reference/simple_stmts.html#the-global-statement
A working example based on your pseudocode would be:
def getA():
global A
return A
def getB():
global B
return B
def setA(value):
global A

It isn't possible to have an uninitialised variable. If it doesn't have
a value then it doesn't exist.
True, but you can use the global statement to refer to the variable
within a function and read from the variable there, without it being
already

You don't need the global statement unless you plan to *write* the

The part I don't know to do is declare the variables, either as globals

Generally, you can use the object None to indicate that something has
