* TypeError - Need help passings args

[Ernesto]

My program is below.  I'm trying to use two Windows ".exe" files with
my command line python interface.  I get user input, then call
"launchWithoutConsole".  This was working OK until I introduced the
'args' part.  Now I get the following error everytime I call
"launchWithoutConsole":

      return subprocess.Popen([command] + args,
startupinfo=startupinfo).wait()

TypeError: can only concatenate list (not "str") to list

I'm not sure if it's the WAY I'm passing it or if it's the function
itself (which I retrieved from
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/409002
)

Please help.  Thanks!

import subprocess

def launchWithoutConsole(command, args):
    """Launches 'command' windowless and waits until finished"""
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    return subprocess.Popen([command] + args,
startupinfo=startupinfo).wait()
