The pylab interface to the matplotlib plotting library has some of the 
characteristics the author of the first link is talking about, but the 
trend has been away from some aspects of that vision, not towards it.

For more about the real pylab, see

Numpy is the common core, providing N-dimensional arrays and math; 
matplotlib is a plotting library, using numpy; scipy is a collection of 
math/science functionality, also using numpy.

But don't forget ipython, which provides a nice interactive shell:
