Hi Dave! thank you very much for your quick reply! I did manage to get the program run from cmd.exe. So does it mean that if I want to use python interactively,I should use the interpreter,while if I just want to run a python program, I should use DOS shell instead? Also, how could I edit my script? I have sth called "IDLE" installed along with python. Is it the right place to write/edit my script? Sorry about these semi-idiot questions but it is really hard to find an article or book that covers such basic stuffs! Thank you! Caroline Hou -- http://mail.python.org/mailman/listinfo/python-list
