Installing Python

Caution

When you are given the option of unchecking any optional components, don't uncheck any! Some of these components can be useful for you, especially IDLE.

An interesting fact is that about 70% of Python downloads are by Windows users. Of course, this doesn't give the complete picture since almost all Linux users will have Python installed already on their systems by default.

Using Python in the Windows command line

If you want to be able to use Python from the Windows command line, then you need to set the PATH variable appropriately.

For Windows 2000, XP, 2003 , click on Control Panel -> System -> Advanced -> Environment Variables. Click on the variable named PATH in the 'System Variables' section, then select Edit and add ;C:\Python23 (without the quotes) to the end of what is already there. Of course, use the appropriate directory name.

For older versions of Windows, add the following line to the file C:\AUTOEXEC.BAT : 'PATH=%PATH%;C:\Python23' (without the quotes) and restart the system. For Windows NT, use theAUTOEXEC.NT file.
