raw_input 是必须按"Enter"才结束的，我希望有一个即时捕捉的功能，比如在控制台下，用户随便按个什么我都能立刻捕捉到，比如用户按了下 Tab。

用ctypes调用windows api(我想通用的console api里不可能有这样的函数。
def playmp3(name):
print name
if name.endswith("mp3"):
indll = 'in_mp3.dll'
else:
indll = 'in_wm.dll'
outdll = 'out_wave.dll'
if init(indll, outdll):
print 'cannot load plugins'
sys.exit(0)
info = fileinfo(name)
#print 'Playing "%s" (%s), press \'q\' to exit ....'%(info[0], name)
play(name)
user32 = ctypes.windll.user32
keystate= None
while 1:
user32.GetAsyncKeyState.restype = WORD
user32.GetAsyncKeyState.argtypes = [ ctypes.c_char ]

if user32.GetAsyncKeyState('Q'):

#
os.system("exit")
break
if user32.GetAsyncKeyState('9') :
quit()
import deltorecyclebin
deltorecyclebin.deltorecyclebinOrig(name)
print "delete" + name
break

if user32.GetAsyncKeyState('P'):
print ((not ispaused()) and "paused" ) or "resumed"
pause(not ispaused())

time.sleep(0.1)
if (gettime() > 0) and (gettime() > getlength() - 3000):
print 'stopped'
break
