推荐答案

0 和 1 是退出代码.

0 and 1 are the exit codes.

exit(0) 表示没有任何错误/问题的干净退出

exit(0) means a clean exit without any errors / problems

exit(1) 表示存在一些问题/错误/问题，这就是程序退出的原因.

exit(1) means there was some issue / error / problem and that is why the program is exiting.

这不是 Python 特有的，而且很常见.非零退出代码被视为异常退出，有时，错误代码会指出问题所在.零错误代码表示成功退出.

This is not Python specific and is pretty common. A non-zero exit code is treated as an abnormal exit, and at times, the error code indicates what the problem was. A zero error code means a successful exit.

这对于其他程序、shell、调用者等了解您的程序发生了什么并相应地进行操作非常有用.

This is useful for other programs, shell, caller etc. to know what happened with your program and proceed accordingly.
