This package will install the MacPython 2.3.5 additions for Mac OS X 10.4. Installation requires approximately 3.3 MB of disk space, ignore the message that it will take zero bytes. You must install onto your current boot disk, even though the installer does not enforce this, otherwise things will not work. This installer does not contain a Python engine, as Apple already includes that in 10.4. It does contain a set of programs to allow easy access to it for Mac users (an integrated development environment, a Python extension package manager) and the waste module. The installer puts the applications in MacPython-2.3 in your Applications folder. The PythonIDE application has a Help command that gets you started quickly with MacPython and contains references to other documentation. More information on MacPython can be found at http://www.cwi.nl/~jack/macpython, more information on Python in general at http://www.python.org.
