Steve, thanks for the input. That is actually what I am trying to do, but I don't know the syntax for this in python. For example here is a list I want to work with as input: [101, 66, 75, 107, 108, 101, 106, 98, 111, 88, 119, 93, 115, 95, 114, 95, 118, 109, 85, 75, 88, 97, 53, 78, 98, 91, 115, 77, 107, 153, 108] Here is as far as I have gotten coding: >>> for num in alist: ... if adict.has_key(num): ... x = adict.get(num) ... x = x + 1 # dont know how to update a value here else: // add key with value one here somehow. Thats where I am at now. For the record, I am not taking a class on python and using this forum to do my homework. I graduated in 1999 and am trying to get familiar with python and refresh my statistics skills. Python seems like it would be a good language to do math/stat work in, in a lightweight way.
Thank for all the help and have a great day! Ed -- http://mail.python.org/mailman/listinfo/python-list
