There are two ways to interact with PyPedal: interactively from a Python command line, and programmatically using a script that is run using the Python interpreter. The latter is preferred to the former for any but trivial examples, although it is useful to work with the command line while learning how to use PyPedal. A number of sample programs are included with the PyPedal distribution.
