copyOfA isn't a copy of a; it's a different name bound to the same object as a. You can verify that: id(a) and id(copyOfA) will return the same value. To make a copy of a (assuming a is a dict), you can do: copyOfA = dict(a) or copyOfA = a.copy() or more generally import copy copyOfA = copy.copy(a) Cheers, Roel -- If I have been able to see further, it was only because I stood on the shoulders of giants. -- Isaac Newton Roel Schroeven -- http://mail.python.org/mailman/listinfo/python-list
