Some of my extra-favorite features of python:
named args in function calls: foo(a=1, b=2)
named string interpolation specifiers: "%(a)s %(b)s" % {'a':'foo', 'b':'bar'}
you can pull a class out of one file and put it in another file, and you only need to put "from newfile import TheClass?" in the old file (and put some imports in the new file). you don't have to change all the references to TheClass? in the original file.
