The Python Standard Library is a collection of script modules accessible to a Python program to simplify the programming process and removing the need to rewrite commonly used commands. They can be used by 'calling/importing' them at the beginning of a script.

A list of the Standard Library modules can be found at http://www.python.org/doc/.

The following are among the most important:

• time
• sys
• os
• math
• random
• pickle
• urllib
• re
• cgi
