But I'm not. I'm building a new list and binding it to the same name as the original, which works perfectly fine (unless I'm missing something): >>> l = range(100) >>> l = [d for d in l if not d % 5] >>> l [0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95] > The for-loop was removing the item where there's a match, so the list > comprehension in this case should keep the item where there _isn't_ a match: > > l = [d for d in l if d['title'] != 'ti'] Now that's a mistake. Cheers for the catch. -- http://mail.python.org/mailman/listinfo/python-list
