  Numpy and SciPy are program libraries for the Python scripting language,
which apply to a large spectrum of numerical and scientific computing tasks.
The Sage project provides a multiplatform software environment which enables
one to use, in a unified way, a large number of software components, including
Numpy and Scipy, and which has Python as its command language. We review
several examples, typical for scientific computation courses, and their
solution using these tools in the Sage environment.
