"self" is a name refering to the particular instance whose method is being
called. If I have
class C:
def __init__(self):
self.x = 7
def printx(self):
print self.x
a = C()
b = C()
If I call a.printx(), self will be bound to the same object a is bound to.
If I call b.printx(), it will be bound to the object b references.
The precise use of the name "self" is indeed simply a convention. You could
call it "barney" if that makes you feel better. ;-)
