[Tutor] PYTHONPATH
In working my way through the book on python, i am working in directories for chapers. Now I am on modules, and some are reused in later chapters. I have set up a directory for the modules. How do I add it to my PYTHONPATH? I can use sys.path.append but that only lasts for the session. -- Bob Rea mailto:pet...@petard.us http://www.petard.us http://www.petard.us/blog http://www.petard.us/gallery ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
