Python imports modules by looking for them in the folders listed in the variable sys.path. sys.path gets populated when Python starts up and includes some standard locations plus any you define in your PYTHONPATH environment variable. You can also modify sys.path yourself at run-time. But basically that means that any files you want to import must be located in a folder in sys.path So either you save them there, or you add the location to sys.path. Personally I save all the modules I will reuse across projects in a PROJECTS\Lib folder which I added to my PYTHONPATH environment variable. Modules that I want to import in the current project only I leave in the current directory. If your project is big you may want to subdivide the modules into a folder heirarchy and Python's package system allows you to do that. But since most beginners won't generate that many modules in a project I'll leave reading about packages as an excercise for the keen student! :-) Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
