Miscellany

For Windows NT, 2000 and (I assume) XP, you will need to add a string such as

;C:\Python23

to the current setting for the PATH environment variable, which you will find in the properties window of "My Computer" under the "Advanced" tab. Note that if you have sufficient privilege you might get a choice of installing the settings either for the Current User or for System. The latter is preferred if you want everybody to be able to run Python on the machine.
