That's not implied by the above, nor is it what I meant. I meant that the relationship is not the same. * The attributes of an object ‘foo’ are what you access via ‘foo.bar’ syntax. You don't access those attributes via ‘foo[bar]’. * The items of a dictionary ‘foo’ are what you access via ‘foo[bar]’ syntax. You don't access those items via ‘foo.bar’. That's an important, and real, difference. And it's much better learned as part of a comprehensive course on Python, not in a deep dive into the magic methods. I really don't know why it's been so difficult to talk about this, but I hope my meaning is clear now. Have a wonderful end of year, folks. -- \ “There are no chaplains in foxholes.” —Sergeant Justin | `\ Griffith, 2011-07-27 | _o__) | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
