This is a great, if somewhat basic list. My $0.02: Python is a tool for thinking clearly. That you can run your "thoughts" as written is a very nice bonus, of course.

There are some really interesting things that Python allows:

    >>> d = {}
    >>> d[23], d[14], d['hmm'] = 'abc'
    >>> d
    {'hmm': 'c', 14: 'b', 23: 'a'}
