Which would make it like dict.__getitem__ and dict.get, which leads to a lot of people using dict.get() because they don't know about subscripting. And then they mask potential errors because they're using the version that suppresses them, since they didn't even know about the other. Not sure that's an improvement. But I do see the logic in the separation. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
