python 获取键盘输入、同时有超时的功能_键盘输入与Python超时

您链接到的示例是错误的，并且在调用警报处理程序而不是读取块时实际发生异常。更好的尝试这个：

import signal

TIMEOUT = 5 # number of seconds your want for timeout

def interrupted(signum, frame):

"called when read times out"

print 'interrupted!'

signal.signal(signal.SIGALRM, interrupted)

def input():

try:

print 'You have 5 seconds to type in your stuff...'

foo = raw_input()

return foo

except:

# timeout

return

# set alarm

signal.alarm(TIMEOUT)

s = input()

# disable the alarm after success

signal.alarm(0)

print 'You typed', s
