请问python杀死windows进程

请教python杀死windows进程
最近在学习python方面的知识,根据这门语言很简洁,挺有意思的,这里想请教大家一个问题。 
  请教下在python中如何杀掉windows中的进程,根据进程名获取进程的ID,我的版本是2.7,没有psutil模块,请教大家下如何实现的,谢谢!

别人写的,转一下:

Python code
import ctypes
import sys

TH32CS_SNAPPROCESS = 0x00000002
class PROCESSENTRY32(ctypes.Structure):
     _fields_ = [("dwSize", ctypes.c_ulong),
                 ("cntUsage", ctypes.c_ulong),
                 ("th32ProcessID", ctypes.c_ulong),
                 ("th32DefaultHeapID", ctypes.c_ulong),
                 ("th32ModuleID", ctypes.c_ulong),
                 ("cntThreads", ctypes.c_ulong),
                 ("th32ParentProcessID", ctypes.c_ulong),
                 ("pcPriClassBase", ctypes.c_ulong),
                 ("dwFlags", ctypes.c_ulong),
                 ("szExeFile", ctypes.c_char * 260)]

def getProcList():
    CreateToolhelp32Snapshot = ctypes.windll.kernel32.CreateToolhelp32Snapshot
    Process32First = ctypes.windll.kernel32.Process32First
    Process32Next = ctypes.windll.kernel32.Process32Next
    CloseHandle = ctypes.windll.kernel32.CloseHandle
    hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)
    pe32 = PROCESSENTRY32()
    pe32.dwSize = ctypes.sizeof(PROCESSENTRY32)
    if Process32First(hProcessSnap,ctypes.byref(pe32)) == False:
        print >> sys.stderr, "Failed getting first process."
        return
    while True:
        yield pe32
        if Process32Next(hProcessSnap,ctypes.byref(pe32)) == False:
            break
    CloseHandle(hProcessSnap)

def getChildPid(pid):
    procList = getProcList()
    for proc in procList:
        if proc.th32ParentProcessID == pid:
            yield proc.th32ProcessID
   
def killPid(pid):
    childList = getChildPid(pid)
    for childPid in childList:
        killPid(childPid)
    handle = ctypes.windll.kernel32.OpenProcess(1, False, pid)
    ctypes.windll.kernel32.TerminateProcess(handle,0)


if __name__ =='__main__':
    args = sys.argv
    if len(args) >1 :
        pid = int(args[1])
        killPid(pid)
    else:
        procList = getProcList()
        for proc in procList:
            print proc.szExeFile+'  '+str(proc.th32ParentProcessID) + '  '+str(proc.th32ProcessID)

# Usage demo

import subprocess
import time

#import winproc

timeout = 2
process = subprocess.Popen("cmd /k ping localhost -t",shell = True)
start = int(time.time())
while process.poll()==None:
    now = int(time.time())
    if int (now - start) >timeout:
        pid = process.pid
        break

winproc.killPid(pid)
       
print "End"

------解决方案--------------------
Python code
import subprocess
import time

import wmi
c = wmi.WMI ()

#
# Kill a process by id
#
notepad = subprocess.Popen (["notepad.exe"])
time.sleep (1)
for process in c.Win32_Process (ProcessId=notepad.pid):
process.Terminate ()

#
# Which process ids correspond to an .exe
#
for i in range (5):
subprocess.Popen (["notepad.exe"])

for process in c.Win32_Process (caption="notepad.exe"):
print process.ProcessId

#
# _Some_ (but not all) of the information about each file
#
for process in c.Win32_Process (caption="notepad.exe"):
print process
process.Terminate ()

Python code
import os

command = 'taskkill /F /IM QQ.exe' #比如杀死QQ进程
os.system(command)
