我有一个python测试脚本应该运行18个小时然后自杀。该脚本对多个设备使用多处理。我从main()函数获得的数据将随时间变化。
我将这三个args传递给多处理中的worker方法。
我怎样才能做到这一点?

如果您不需要担心子进程上的清理太多,您可以使用.terminate()
...
time.sleep(18 * 60 * 60) # go to sleep for 18 hours
children = multiprocessing.active_children()
for child in children:
child.terminate()
for child in multiprocessing.active_children():
child.join() # wait for the children to terminate
如果你确实需要在所有子进程中进行一些清理,那么你需要修改它们的运行循环(我假设while True
)来监视时间的流逝,并且只有第二个while循环在主程序,等待孩子自己离开。

你永远不会将datetime.now()与test_ended_time进行比较。
