How do I find out which directories are listed in my system’s
PYTHONPATH variable, from within a Python script (or the interactive shell)?
sys.path might include items that aren't specifically in your
PYTHONPATH environment variable. To query the variable directly, use:
import os try: user_paths = os.environ['PYTHONPATH'].split(os.pathsep) except KeyError: user_paths = 
You would probably also want this:
import sys print(sys.path)
Or as a one liner from the terminal:
python -c "import sys; print('\n'.join(sys.path))"
