python 获取键盘输入,同时有超时的功能示例

如下所示：'''###getkeyboardinputandtimeout=5importsys,time,msvcrtdefreadInput(caption,default,timeout=5):start_time

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
