python的系统调用

一 python使用CreateProcess函数运行其他程序

>>> import win32process
>>> handle = win32process.CreateProcess('c:\\windows\\notepad.exe','',None,None,0,win32process.CREATE_NO_WINDOW,None,None,win32process.STARTUPINFO())
>>> win32process.TerminateProcess(handle[0],0)
>>> import win32event
>>> handle = win32process.CreateProcess('c:\\windows\\notepad.exe','',None,None,0,win32process.CREATE_NO_WINDOW,None,None,win32process.STARTUPINFO())
>>> win32event.WaitForSingleObject(handle[0],-1)
0

 

二 ctypes模块简介

以下代码是使用ctype模块在windows下直接调用user32.dll中的MessageBoxA函数。

>>> from ctypes import *
>>> user32 = windll.LoadLibrary('user32.dll')
>>> user32.MessageBoxA(0,str.encode('Ctype is cool!'),str.encode('Ctype'),0)
