0and 1are exit codes, and they are not necessarily python specific, in fact they are very common.
0和1是退出代码，它们不一定是特定于python的，实际上它们很常见。
exit code (0)means an exit without an errors or issues.
exit code (0)表示没有错误或问题的退出。
exit code (1)means there was some issue / problem which caused the program to exit.
exit code (1)意味着有一些问题/问题导致程序退出。
The effect of each of these codes can vary between operating systems, but with Python should be fairly consistent.
这些代码中的每一个的效果可能因操作系统而异，但 Python 应该相当一致。

0and 1are exit codes.
0和1是退出代码。
exit code (0)means an exit without an errors or any issues, can be a compile time error or any dependency issue.
exit code (0)意味着没有错误或任何问题的退出，可能是编译时错误或任何依赖问题。
exit code (1)means there was some issue which caused the program to exit. For example if your program is running on port :8080and that port is currently in used or not closed, then you code ends up with exit code 1
exit code (1)意味着有一些问题导致程序退出。例如，如果您的程序正在运行port :8080并且该端口当前正在使用或未关闭，那么您的代码最终会exit code 1
