python 获取键盘输入,同时有超时的功能示例

'''###get keyboard input and timeout =5import sys, time, msvcrtdef readInput( caption, default, timeout = 5): start_time = time.time() sys.stdout.write('%s(%s):'%(caption, default)); input = '' while True:  if msvcrt.kbhit():   chr = msvcrt.getche()   if ord(chr) == 13: # enter_key    break   elif ord(chr) >= 32: #space_char    input += chr  if len(input) == 0 and (time.time() - start_time) > timeout:   break print '' # needed to move to next line if len(input) > 0:  return input else:  return default  readInput("TEst1",10)'''###catch keyboard input, if key == ESC, stop import sys, time, msvcrtdef readKeyBoardInput(timeout = 5): start_time = time.time() sys.stdout.write("If you want to stop test process,please click ESC button"); input = '' while True:  if msvcrt.kbhit():   chr = msvcrt.getche()   if ord(chr) == 27: # ESC    return True  if len(input) == 0 and (time.time() - start_time) > timeout:   return False
