Python Basics in pdf

This tutorial is structured around the idea that you want to get up and running with Python using PyLab as quickly as possible. The first question I asked my myself before I started using PyLab was why consider Python? What makes it a vialble alternative to other languages available for scientific and engineering computations and simulations? OK, everyone has favorites, and presently MATLAB is very popular in the signals and system community. Is there a need to change? This is a debate that lies outside the scope of this tutorial, but the ability to use open-source tools that work really, really well is very compelling.
