pandas in the IPython Notebook

I finally got around to playing a tiny bit with pandas today and was delighted when I saw its representation in the IPython notebook. Take a look in the PDF.

IPython detects a special _repr_html_ method on (in this case) the pandas DataFrame object and uses that for the output instead of the usual __str__ or __repr__ methods. Here _repr_html_ returns the contents of the DataFrame in an HTML table, which is also useful for posting to a blog:

Ant Bat Cat Dog
0 0 1 2 3
1 4 5 6 7
2 8 9 10 11
3 12 13 14 15
4 16 17 18 19

This is another great feature of the IPython notebook and I look forward to it popping up in more places!
