len() is not the same as __len__. The built in len() function does type checking and produces a useful exception/message if you provide an argument for which len() is inappropriate. Instead, if you do someobj.__len__ and that object

That defense doesn't really hold up. len() makes no sense for numbers, booleans, None, and probably other types I cannot think of at the moment. Python has a LONG list of built in functions, most of which are only applicable to a few t

No offense to people who are good people and put in great effort, but that alone does not mean one is infallible. Python is a very poorly designed language, and when I would sometimes dig to find out why things here how they were, Guido was

Having annoying or disturbing loud human noises over the PA system for the entire flight is not something one does to "arouse curiousity". There's no way this is a sanctioned AA marketing program.
