python在windows下创建隐藏窗口子进程的方法

import subprocess
IS_WIN32 = 'win32' in str(sys.platform).lower()
def subprocess_call(*args, **kwargs):
 #also works for Popen. 
 #It creates a new *hidden* window, 
 #so it will work in frozen apps (.exe).
 if IS_WIN32:
 startupinfo = subprocess.STARTUPINFO()
 startupinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE | subprocess.STARTF_USESHOWWINDOW
 startupinfo.wShowWindow = subprocess.SW_HIDE
 kwargs['startupinfo'] = startupinfo
 retcode = subprocess.call(*args, **kwargs)
 return retcode
