我可以关闭在Python中用subprocess.Popen打开的CMD窗口吗？ [英] Can I close the CMD window that opened with subprocess.Popen in Python?

问题描述

我有一个程序，需要在新CMD中运行小任务。
例如：

I have a program that need to run small tasks in new CMDs. For example:

def main()
    some code
    ...
    proc = subprocess.Popen("start.bat")
    some code...
    proc.kill()

子进程，Popen打开一个新的cmd窗口并在其中运行 start.bat。
proc.kill（）终止进程，但不关闭cmd窗口。
是否可以关闭此cmd窗口？

subprocess,Popen opens a new cmd window and runs "start.bat" in it. proc.kill() kills the process but doesn't close the cmd window. Is there a way to close this cmd window?

我考虑过命名打开的cmd窗口，以便可以使用以下命令将其杀死：

I thought about naming the opened cmd window so i can kill it with the command:

/taskkill /f /im cmdName.exe

是否可以？如果否，您有什么建议？

Is it possible ?if no, What do you suggest ?

编辑，添加了最小，完整和可验证的示例：

Edit, Added Minimal, Complete, and Verifiable example:

a.py：

import subprocess,time
proc = subprocess.Popen("c.bat",creationflags=subprocess.CREATE_NEW_CONSOLE)
time.sleep(5)
proc.kill()

b.py

while True:
    print("IN")

c.bat

python b.py

推荐答案

运行子进程时期望的。您只是在杀死 .bat 过程。

that's expected when a subprocess is running. You're just killing the .bat process.

您可以使用 psutil （第三方，使用 pip install psutil 安装）来计算子进程&杀死他们，像这样：

You can use psutil (third party, use pip install psutil to install) to compute the child processes & kill them, like this:

import subprocess,time,psutil
proc = subprocess.Popen("c.bat",creationflags=subprocess.CREATE_NEW_CONSOLE)
time.sleep(5)

pobj = psutil.Process(proc.pid)
# list children & kill them
for c in pobj.children(recursive=True):
    c.kill()
pobj.kill()

通过您的示例进行测试，该窗口在5秒钟后关闭

tested with your example, the window closes after 5 seconds
