This is a simple generator that will use psutil to get a list of the running python scripts, returned as absolute paths. It attempts (probably correctly) to parse the Python invocation command line.

Will consider "python binaries" any executable that matches python*. Will skip any process it can't get the CWD of (probably catches only processes by the same user, or all if you run it as root)
