I do have Python 3 installed. Actually I have Python 2 installed but IDLE defaults to Python 3. So it is a pain to actually load Python 2. Range(10) stores the min max values and loads each number in between when needed. Ian explained that very clearly. I tried list(range(10) I thought that would work in Python 3. It didn't. I spent quite a bit of time last night trying to come up with the right combination of str and int commands to make range(10) work with my simple example. It didn't. I am pretty frustrated. I am just skipping that little bit of code for the moment. Thanks everyone for your suggestions. -- https://mail.python.org/mailman/listinfo/python-list
