python+psutil kill 指定进程

当我们想在程序中结束掉某个已知的任务时
1,获取系统所有pid，pname
2，循环根据name找到指定程序的pid
3，kill（subprocess.Popen("cmd.exe /k taskkill /F /T /PID %i" % pid, shell=True)）

举例：杀死我本机的navicat任务

import psutil
def kill_process(name):
    pids = psutil.pids()
    for pid in pids:
        p = psutil.Process(pid)
        process_name = p.name()
        if name in process_name:
            print("Process name is: %s, pid is: %s" % (process_name, pid))  # 1,33664
            try:
                import subprocess
                subprocess.Popen("cmd.exe /k taskkill /F /T /PID %i" % pid, shell=True)
            except OSError:
                print('没有此进程!!!')
kill_process('navicat')
