How to view Python environment variables

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.
