To view the environment variables in Python and query for a particular one:
import os print(os.environ) # Print a dict of env vars and their values os.environ["PYTHONPATH"] # Query a specific env var
Python picks up these environment variables from your shell when it is first invoked. So this is useful to check if your shell environment variables and their values are being correctly imported into Python.
