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?

os.environ is a bunch of functions to read and write the system environment and os.environ.get() returns an environment variable. See this documnetation page for some details.

Most OS's have environment variables -- for example, the $PATH variable. Python runs within the OS, and sometimes has need of those environment variables. They can be accessed through the os.environ dict.
