Sandro,
Firstly, good luck with the book.
The sort of book I'd buy would explain how to use the combination of
matplotlib/ipython/scipy/numpy to analyse data.

Hello again,
I finally found the command I was looking for. It is the to_polygons().
Here is what worked :
# make a LineCollection of contours
col=contour(X,Y,Z,LevelsNumber).collections
for i in np.arange(0,LevelsNumber,1):
polygoni=col[i].get_paths()[0].to_polygons()[0]
print polygoni
