This blocking function will start a process and wait until the new process exits before moving on. The documentation recommends using run() for all cases that it can handle. For edge cases where you need more control, the Popen class can be used. Popen is the underlying class for the ...
1 pid = subprocess.Popen([sys.executable,"longtask.py"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)我没有在其他平台上检查过代码,也不知道freebsd上行为的原因。如果有人知道,请分享你的想法。在Python中搜索启动后台进程还没有给出任何答案。相关讨论 我注意到在pydev+...
# 使用 subprocess 执行命令 process = subprocess.Popen(execute_command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) # 等待较长时间,例如 30 秒 timeout_seconds = 30 start_time = time.time() while time.time() - start_time < timeout_seconds: if process.poll() is not None:...
Python中有许多种运行子进程的方式,如popen、popen2和os.exec*等。对于当今的Python来说,最好用且最简单的子进程管理模块,应该是内置的subprocess模块。用subprocess模块运行子进程,是比较简单的。subprocess模块让我们非常方便地启动一个子进程,并且控制其输入输出。
执行shell命令时,推荐使用p=subprocess.Popen,可以实时获取执行进度,通过readline或者readlines或者p.wait函数皆可以阻塞shell命令 如果将subprocess.Popen放在thread中,不仅需要停止线程,还需要停止进程,即线程设置为守护,进程调用p.kill结束,两个都调用才能结束当前执行的任务 ...
