Alex:
Thanks for the example. I too had been wondering about this for a
while.
One question though, which I haven't been able to find the answer from
scouring the internet. What is the difference between calling
__setattr__ and setattr or __getattr__ and getattr, for that matter?

thanks

class Person(object):
def __init__(self):

def newAttribute(self,name,value=None):
setattr(self,name, value)
def newAttribute2(self,name,value=None):
self.__setattr__(name, value)
def dump(self):
for self.y in self.__dict__.keys():
yield self.y + "=" + getattr(self,self.y)
p1 = Person()
p1.newAttribute('fname','Brian')
p1.newAttribute('lname','Munroe')
p1.newAttribute2("mi","E")
for x in p1.dump():
print x
