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
Simple Question regarding running .py program
Hi all! I just started learning Python by myself and I have an extremely simple question now! I am in my Python interpreter now and I want to open/edit a program called nobel.py. But when I typed >>> python nobel.py, it gave me a "SyntaxError:invalid syntax”( I've changed to the correct directory)what should I do? I also want to run the program, but as I double-clicked the program, a command window pops up and closes immediately. How can I see the result of the program run? Could anyone help me please? I am pretty confused here...Thank you! -- http://mail.python.org/mailman/listinfo/python-list
