This tutorial gives an introduction to the IPython interactive shell for exploratory computing with python. In order to follow along with the tutorial, you must have at least the following four packages installed: 1) python 2) ipython 3) numpy 4) matplotlib For instructions on how to install these packages on your platform, see: http://ipython.org/install.html The tutorial uses a data set, stored in rawSignals.txt, as a basis for showing off some of the utilities of IPython. A cleaned-up and commented log of the ipython session created during the live tutorial will be added afterwards.
