请问怎样监控多个进程的运行状态

[PandaFromUniverse]

最近想写一个脚本 可以监控本地进程(比如迅雷、微信、.bat文件）是否在运行
如果检测到进程不存在，就启动进程

import os
import psutil

def find_procs_by_name(name):
    "Return a list of processes matching 'name'."
    assert name, name
    ls = []
    for p in psutil.process_iter():
        name_, exe, cmdline = "", "", []
        try:
            name_ = p.name()
            cmdline = p.cmdline()
            exe = p.exe()
        except (psutil.AccessDenied, psutil.ZombieProcess):
            pass
        except psutil.NoSuchProcess:
            continue
        if name == name_ or cmdline[0] == name or os.path.basename(exe) == name:
            ls.append(name)
    return ls

引用 1 楼 oyljerry 的回复:

import os
import psutil

def find_procs_by_name(name):
    "Return a list of processes matching 'name'."
    assert name, name
    ls = []
    for p in psutil.process_iter():
        name_, exe, cmdline = "", "", []
        try:
            name_ = p.name()
            cmdline = p.cmdline()
            exe = p.exe()
        except (psutil.AccessDenied, psutil.ZombieProcess):
            pass
        except psutil.NoSuchProcess:
            continue
        if name == name_ or cmdline[0] == name or os.path.basename(exe) == name:
            ls.append(name)
    return ls

这个传递进去的是什么值? 我传参出现了 IndexError: list index out of range

OK了 我自己搞定了 用了win32com的方法
