Blogspam, copied (without author's permission?) from http://www.johndcook.com/blog/2012/10/24/python-for-data-ana... . [EDITED to add: actually, it looks like it was with the author's position. Still blogspam. Incidentally, John Cook's blog is frequently updated and frequently interesting, at least for anyone with an interest in mathematics and software.]
