Cookies from a previous request made in the currently running

ran the program?

Examine this code and its output:
class SmartRequest(object):
def __init__(self, id):
if not getattr(SmartRequest, 'cj', None):
SmartRequest.cj = "I'm a cookie jar. Created by request:
%s" % id
r1 = SmartRequest(1)
r2 = SmartRequest(2)
print r1.cj
print r2.cj
--output:--
I'm a cookie jar. Created by request: 1
I'm a cookie jar. Created by request: 1
