Python in a Nutshell

Name

exit

Synopsis

exit(arg=0)

Raises a SystemExit exception, which normally terminates execution after executing cleanup handlers installed by try/finally statements. If arg is an integer, Python uses arg as the program’s exit code: 0 indicates successful termination, while any other value indicates unsuccessful termination of the program. Most platforms require exit codes to be between 0 and 127. If arg is not an integer, Python prints arg to sys.stderr, and the exit code of the program is 1 (i.e., a generic unsuccessful termination code).
