Your analysis is correct, and it's because of the bracketing. Just as you learned back in maths class (or math class, if you're that sort), you start from the innermost brackets and work your way out. In fact, the nested example starts with the main loop, and for each value it goes through, it creates the entire inner comprehension. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
