Both virtualenv and venv set the environment variable $VIRTUAL_ENV when activating an environment. See PEP 405. You can read out this variable in shell scripts, or use this Python code to determine if it's set. The problem is, this only works when the environment is activated by the activate shell script.

Of course, only one interpreter can be the default application for Python file types.
