Python Operating system environment variables

The way to get the entire system variable is Os.environ, which is an OS class type that can be converted to a dictionary type when used

Environ_value = Dict (Os.environ)

So you can see all the Key,environ_value.keys ()

You can also see all the Value,environ_value.values ()

Get a single key-value,environ_value.get (' PATH ')

Add a new environment variable method

Git_path = ' C:\\Program Files (x86) \\Git\\bin '
os.environ["path"] = Git_path + ";" + os.environ["path"]
