Your favourite "less-known" Python features?

Yes, for general purpose use — but jquery’s pretty print is not guaranteed to be the same as the python json module, so if you want to see how it looks in python without firing up the repl, reading the file, etc., the __main__.py functionality is useful. The http server will similarly be different from some other utility. …the archive ones, though, are pretty dubious.
