本文提供Python中获取键盘输入并设置超时功能的代码示例。通过msvcrt模块实现字符读取与时间判断，支持默认值返回及ESC键终止逻辑，适用于需要限制用户等待时间的交互场景。

具体实现代码如下所示：

'''
###get keyboard input and timeout =5

import sys, time, msvcrt

def 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, msvcrt

def 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
