I think your problem here may be with how you're trying to parse that datetime. There are two common ways to get access to a thing called "datetime": # Option 1: import datetime # Option 2: from datetime import datetime The first one gives you a module; the second gives you just one class out of that module (one that happens to have the same name as the module itself). My guess is that you're using the first form, but you picked up some example code from somewhere that assumes the second. Try using "datetime.datetime.strptime" in your key function, and see if that helps. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
