Replacing Shell Scripts: Accessing Environment Variables from Python

At times, you will have to get and set environment variables to get the desired effect in your scripts. The os module offers this function through a dictionary like object called environ.

import os
homedir = os.environ['HOME']
if not '/opt/mysuite/bin' in os.environ['PATH']:
    os.environ['PATH'] += ':/opt/mysuite/bin'
os.system('mysuiteapp') # Executable in /opt/mysuite/bin
