I'm sure with a little effort and a few experiments on the commandline you can answer your question yourself. Please limit your posts to c.l.py to those questions that are a little harder. Hint: when you experiment with nested lists use numbers, not strings as list entries that are not lists themselves. Strings can confuse you about the nesting level: >>> items = ["foo"] >>> items[0] 'foo' >>> items[0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0] 'f' -- https://mail.python.org/mailman/listinfo/python-list
