Python Programming for Biology: Bioinformatics and Beyond

The ‘

os

’ module

The os module is used for things that depend on the operating system (whether Windows,

Mac OS X, Linux etc.) and presents them in a standardised way. For example, os.path  is

used to interact with the file system. We’ve skipped the description of lots of functionality

involving  processes,  devices  etc.,  concentrating  only  on  a  few  of  the  more  commonly

used, general functions. This module should not be confused with the sys module, which

deals with Python interpreter information and not the operating system.
