The only guarantee is testing it on both yourself. Some modules are inherently os-dependant (much of the 'os' module for example), and some constructs just don't work on all platforms (using os.environ['LOGNAME'] or system('cat file') as examples). If you stick to python code that doesn't touch the OS directly, you won't (read: shouldn't) have a problem, but when you start interacting with the OS directly you have to think hard about what you're doing. --Buck -- http://mail.python.org/mailman/listinfo/python-list
