"requires a parameter from elsewhere in the imported module" is a concept I don't understand. Here is what I think that you need to do in your main script: import sys import otp_encrypt the_key = opt_encrypt.get_key(sys.argv[1]) If that isn't what you want, you'll need to explain the sentence that starts "Now I understand", with examples of what you have tried. BTW, how is the uppercase function different from string.upper, and why aren't you using string methods e.g. otp = otp.upper() ? -- http://mail.python.org/mailman/listinfo/python-list
