Today I saw an article "What's your favorite programming language?" LinuxWeek proncetaj of a 26% (1074 votes) ...
In python "module" which is actually a library.
Using it is simple: import "module name"
See example below:
import os
For example I chose an example of how to display modules that are installed. Open the python command line and run the examples below:
C:\Python32>python
Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> help('modules')
Please wait a moment while I gather a list of all available modules...
