5.3 执行结束后,Python调用自己的exit函数销毁Python解释器(比如销毁其中的全部Python变量),其中的最后一步是调用操作系统的exit函数退出进程。 例如,当我们执行下面这段Python代码时: import os class Track: def __init__(self): print(f'{os.getpid()=} object created in {__name__=}') def __getstate...
If check is True and the exit code was non-zero, it raises a CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute, and output & stderr attributes if those streams were captured. # timeout is not None, 且进程耗时过长, 抛出 TimeoutExpired...
join只能join住start开启的进程,而不能join住run开启的进程 属性介绍: 1 p.daemon:默认值为False,如果设为True,代表p为后台运行的守护进程,当p的父进程终止时,p也随之终止,并且设定为True后,p不能创建自己的新进程,必须在p.start()之前设置 2 3 p.name:进程的名称 4 5 p.pid:进程的pid 6 7 p.exit...
