The following is the code. When I run, I got an error message, saying that \"name exit is not defined\". Could anyone tell me why? Thanks very much for your time and attent

    You need to import sys first, since exit (and argv) is in that module.

    The error I get when I run your code is:

    File "", line 1, in NameError: name 'sys' is not defined

    which is complaining about sys.argv instead of exit. But in either case, the solution -- import sys is the same.

    If you imported sys then use sys.exit(0) - change 0 with any result code you want to exit with. I had the same issue that before compilation when running from .py file exit(0) worked well but after compiling to .exe it gave me an error. I had to change exit(0) to sys.exit(0) and it worked.
