10.4 Error Output Redirection and Program Termination

The ‘sys’ module also has attributes for stdin, stdout, and stderr. The latter is useful for emitting warnings and error messages to make them visible even when stdout has been redirected:

    >>> sys.stderr.write('Warning, log file not found\n')
    Warning, log file not found

The most direct way to terminate a script is to use ‘sys.exit()’.
