When discussing python, the authors missed the elephant in the room: numpy.

When almost any statistical work is done in python, we use numpy arrays, sometimes via the pandas or statsmodels etc. libraries. We seldom use native python types.

This was from 2008: NumPy existed but it was pretty early days (and a pain to install). I'm not sure if pandas had started at that point.
