Here is an example of the input list: [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, 101]
Here is the code I am working on now: >>> for num in alist: ... if adict.has_key(num): ... x = adict.get(num) ... x = x + 1 // update the value here else // add the new value here. Its these two commented out lines that I am working on. For the record, I am not in a python class. I am trying to learn python. For one thing I thought it looks like it would be a good tool to work with math and statistics stuff. Thanks for the help. Have a great day. Ed -- http://mail.python.org/mailman/listinfo/python-list
