print('Gracefully stopping the program.') sys.exit(0) signal.signal(signal.SIGINT, signal_handler) signal.signal(signal.SIGTERM, signal_handler) while True: pass # Your main program logic here 这样,当使用kill命令发送SIGTERM信号时,程序将执行清理操作,然后优雅地退出。 总结 在Linux中停止Python程序的...

这样,脚本将每分钟执行一次,自动结束指定的Python进程。 五、使用PYTHON信号处理 在更高级的场景中,可以使用Python的信号处理来优雅地终止程序。 捕获信号 Python提供了signal模块,可以用于捕获信号并执行相应的处理: import signal import sys def signal_handler(sig, frame): print('Exiting gracefully') sys.exit(0...
That’s because if the subprocess fails, then that usually means that your script has failed.However, if you have a more complex program, then you may want to handle errors more gracefully. For instance, you may need to call many processes over a long period of time. For this, you can...
This loop has two exit conditions. The first condition checks whether the password is correct. The second condition checks whether the user has reached the maximum number of attempts to provide a correct password. Both conditions include abreakstatement to finish the loop gracefully. ...
As is standard practice in theUNIXworld, when the script is passed flags it doesn't understand, you print out a summary of proper usage and exit gracefully. Note that I haven't shown theusagefunction here. You would still need to code that somewhere and have it print out the appropriate...
要在使用 nohup 命令运行 Python 脚本时处理信号中断,你可以使用 signal 模块来捕获和处理这些信号。以下是一个示例: import signal import sys import time def signal_handler(sig, frame): print('Signal {} received. Exiting gracefully.'.format(sig)) sys.exit(0) if __name__ == '__main__': #...
另外,你可以在一个 actor 内部手动删除 actors,使用 ray.actor.exit_actor,或者通过一个 actor 的句柄 ray.kill(account_actor)。如果你知道不再需要特定的 actors 并且想要回收资源,这将会很有用。 正如这里所示,创建一个基本的 Ray actor 并管理其生命周期是相当容易的,但是如果运行 actor 的 Ray 节点由于某种...

1、list can holdarbitraryobjects and can expand dynamically as new items are added. A list is anorderedset of items. 2、A tuple is animmutablelist. A tuple can not be changed in any way once it is created. 3、A set is anunordered“bag”of uniquevalues. A single set can contain valu...
