Function of os.environ in python

Question

I am new to python.I am not having any Knowledge of Python, i came across following line of python code

os.environ.get('IS_THIS_POSSIBLE', 'FALSE') == 'TRUE'

what does os.environ.get Do? Is it accessing something particular to OS internals.

Answer 1

Yes, it is getting operation system's environment variables. For your code, it's returning the value of os-environment variable 'ENABLE_BONDING_ROUTER', return 'FALSE' if it does not exist.

To set an environment variable see the following post on Super User: What are PATH and other environment variables, and how can I set or use them?
