If you wish to do the programming exercises on your own computer you will
need to install four software packages: the main Python language, and the
visual (also called "vpython" in some places), all of which
are available for free as downloads from the web. The simplest way to
install the packages is as follows.
visualpackage. Then click on the "download" link for your operating system, Windows or Macintosh, which will take you to the download page. (The packages are also available for users of the Linux operating system. The installation procedure is more complicated for Linux, but if you are a Linux user you probably already know what you're doing.)
visualpackage (also called "vpython"). (If you are a Windows user this will automatically install the
numpypackage for you as well. If you use a Mac, see step 5 below.)
matplotlibpackage. To do this you should go to this page and click on the link for the latest version of
matplotlib, which at the time of writing is version 1.1.0. You will be presented with a list of packages for different computers. Select and install the one that corresponds to your computer and the version of Python that you installed. For instance, you would click on
matplotlib-1.1.0.win32-py2.7.exefor a Windows computer with Python version 2.7 installed.
numpy. (If you use Windows,
numpywill already have been installed for you when you installed
visual.) Download the latest version of
numpyfrom here and install.
