Python book for a non-programmer

[Simon Brunning]

I have a non-programming friend who wants to learn Python. It's been
so long since I've been in her shoes that I don't feel qualified to
judge the books aimed at people in her situation. I know of two such
books:

<http://www.ibiblio.org/obp/thinkCSpy/>

Any recommendations, or otherwise?
