Python+CMD+任务列表(windows)

Python+CMD+tasklist (windows)

import os
os.system('tasklist')

如何从此命令中提取任何内容?它显示了所有任务,但是当我执行 print(os.system('tasklist')) 时,它打印出 0。 是否可以使此代码有用?

这是访问我认为您正在寻找的数据的另一种方式:

import subprocess

subprocess.getoutput('tasklist').split('\n')

# ['',
#  'Image Name                     PID Session Name        Session#    Mem Usage',
#  '========================= ======== ================ =========== ============',
#  'System Idle Process              0 Services                   0         24 K',
#  'System                           4 Services                   0         44 K',
#  'smss.exe                       284 Services                   0         80 K',
#  'csrss.exe                      384 Services                   0      1,660 K',
#  'wininit.exe                    448 Services                   0        156 K',
#  'csrss.exe                      480 Console                    1     10,996 K',
#  'services.exe                   516 Services                   0      5,440 K',
#  'winlogon.exe                   540 Console                    1      2,196 K',
