最佳答案

The example you have linked to is wrong and the exception is actually occuring when calling alarm handler instead of when read blocks. Better try this:

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

Using a select call is shorter, and should be much more portable

import sys, select


print "You have ten seconds to answer!"


i, o, e = select.select( [sys.stdin], [], [], 10 )


if (i):
print "You said", sys.stdin.readline().strip()
else:
print "You said nothing!"

And here's one that works on Windows

I haven't been able to get any of these examples to work on Windows so I've merged some different StackOverflow answers to get the following:


import threading, msvcrt
import sys


def readInput(caption, default, timeout = 5):
class KeyboardThread(threading.Thread):
def run(self):
self.timedout = False
self.input = ''
while True:
if msvcrt.kbhit():
chr = msvcrt.getche()
if ord(chr) == 13:
break
elif ord(chr) >= 32:
self.input += chr
if len(self.input) == 0 and self.timedout:
break




sys.stdout.write('%s(%s):'%(caption, default));
result = default
it = KeyboardThread()
it.start()
it.join(timeout)
it.timedout = True
if len(it.input) > 0:
# wait for rest of input
it.join()
result = it.input
print ''  # needed to move to next line
return result


# and some examples of usage
ans = readInput('Please type a name', 'john')
print 'The name is %s' % ans
ans = readInput('Please enter a number', 10 )
print 'The number is %s' % ans

A late answer :)

I would do something like this:

from time import sleep


print('Please provide input in 20 seconds! (Hit Ctrl-C to start)')
try:
for i in range(0,20):
sleep(1) # could use a backward counter to be preeety :)
print('No input is given.')
except KeyboardInterrupt:
raw_input('Input x:')
print('You, you! You know something.')

I know this is not the same but many real life problem could be solved this way. (I usually need timeout for user input when I want something to continue running if the user not there at the moment.)

Hope this at least partially helps. (If anyone reads it anyway :) )

I spent a good twenty minutes or so on this, so I thought it was worth a shot to put this up here. It is directly building off of user137673's answer, though. I found it most useful to do something like this:

#! /usr/bin/env python


import signal


timeout = None


def main():
inp = stdinWait("You have 5 seconds to type text and press <Enter>... ", "[no text]", 5, "Aw man! You ran out of time!!")
if not timeout:
print "You entered", inp
else:
print "You didn't enter anything because I'm on a tight schedule!"


def stdinWait(text, default, time, timeoutDisplay = None, **kwargs):
signal.signal(signal.SIGALRM, interrupt)
signal.alarm(time) # sets timeout
global timeout
try:
inp = raw_input(text)
signal.alarm(0)
timeout = False
except (KeyboardInterrupt):
printInterrupt = kwargs.get("printInterrupt", True)
if printInterrupt:
print "Keyboard interrupt"
timeout = True # Do this so you don't mistakenly get input when there is none
inp = default
except:
timeout = True
if not timeoutDisplay is None:
print timeoutDisplay
signal.alarm(0)
inp = default
return inp


def interrupt(signum, frame):
raise Exception("")

Not a Python solution, but...

I ran in to this problem with a script running under CentOS (Linux), and what worked for my situation was just running the Bash "read -t" command in a subprocess. Brutal disgusting hack, I know, but I feel guilty enough about how well it worked that I wanted to share it with everyone here.

import subprocess
subprocess.call('read -t 30', shell=True)

All I needed was something that waited for 30 seconds unless the ENTER key was pressed. This worked great.

Analogous to Locane's for windows:

import subprocess
subprocess.call('timeout /T 30')

Paul's answer did not quite work. Modified code below which works for me on

Following code worked for me.

I used two threads one to get the raw_Input and another to wait for a specific time. If any of the thread exits, both the thread is terminated and returned.

def _input(msg, q):
ra = raw_input(msg)
if ra:
q.put(ra)
else:
q.put("None")
return


def _slp(tm, q):
time.sleep(tm)
q.put("Timeout")
return


def wait_for_input(msg="Press Enter to continue", time=10):
q = Queue.Queue()
th = threading.Thread(target=_input, args=(msg, q,))
tt = threading.Thread(target=_slp, args=(time, q,))


th.start()
tt.start()
ret = None
while True:
ret = q.get()
if ret:
th._Thread__stop()
tt._Thread__stop()
return ret
return ret


print time.ctime()
t= wait_for_input()

Here is a portable and simple Python 3 solution using threads. This is the only one that worked for me while being cross-platform.

Modified iperov answer that works for me (python3 win10 2019-12-09)

replace str with sstr as str is a function in python
add imports
add sleep to lower cpu usage of the while loop (?)

add if name=='main': #required by multiprocessing on windows

sys.stdin = os.fdopen(stdin_fd)
try:

sq.put(False)


def input_in_time(sstr, max_time_sec):

p.start()
t = time.time()
inp = False
while True:


if not sq.empty():
inp = sq.get()
break
if time.time() - t > max_time_sec:
break


tleft=int( (t+max_time_sec)-time.time())
if tleft<max_time_sec-1 and tleft>0:

This is the way I approached this problem. I haven't tested it thoroughly, and I'm not sure it doesn't have some important problems, but considering other solutions are far from perfect as well, I decided to share:

import sys
import subprocess




def switch():
if len(sys.argv) == 1:
main()
elif sys.argv[1] == "inp":
print(input(''))
else:
print("Wrong arguments:", sys.argv[1:])




def main():
passw = input_timed('You have 10 seconds to enter password:', timeout=10)
if passw is None:
print("Time's out! You explode!")
elif passw == "PasswordShmashword":
print("H-h-how did you know you h-h-hacker")
else:
print("I spare your life because you at least tried")




def input_timed(*args, timeout, **kwargs):
"""
Print a message and await user input - return None if timedout
:param args: positional arguments passed to print()
:param timeout: number of seconds to wait before returning None

print(*args, **kwargs)
try:
out: bytes = subprocess.run(["python", sys.argv[0], "inp"], capture_output=True, timeout=timeout).stdout

For Linux, I would prefer the select version by @Pontus. Here just a python3 function works like read in shell:

import sys, select


def timeout_input(prompt, timeout=3, default=""):
print(prompt, end=': ', flush=True)
inputs, outputs, errors = select.select([sys.stdin], [], [], timeout)
print()
return (0, sys.stdin.readline().strip()) if inputs else (-1, default)

Run

In [29]: timeout_input("Continue? (Y/n)", 3, "y")
Continue? (Y/n):
Out[29]: (-1, 'y')


In [30]: timeout_input("Continue? (Y/n)", 3, "y")
Continue? (Y/n): n


Out[30]: (0, 'n')

And a yes_or_no function

In [33]: yes_or_no_3 = lambda prompt: 'n' not in timeout_input(prompt + "? (Y/n)", 3, default="y")[1].lower()


In [34]: yes_or_no_3("Continue")
Continue? (Y/n):
Out[34]: True


In [35]: yes_or_no_3("Continue")
Continue? (Y/n): no


Out[35]: False

Solution inspired by iperov's answer which is hopefully a bit cleaner:

import multiprocessing
import sys


def input_with_timeout(prompt, timeout=None):
"""Requests the user to enter a code at the command line."""
queue = multiprocessing.Queue()
process = multiprocessing.Process(
_input_with_timeout_process, args=(sys.stdin.fileno(), queue, prompt),
)
process.start()
try:
process.join(timeout)
if process.is_alive():
raise ValueError("Timed out waiting for input.")
return queue.get()
finally:
process.terminate()




def _input_with_timeout_process(stdin_file_descriptor, queue, prompt):
sys.stdin = os.fdopen(stdin_file_descriptor)

It's been years already, but just incase someone bumps into this like I did recently trying to solve this sort of problem, there is an easy and faster way of achieving this using the func-timeout package. It has to be installed before use for most IDEs; you can install it via pip. The above link is self explanatory, but I will give an example on how I implemented it.

from func_timeout import FunctionTimedOut, func_timeout


try:
ans = func_timeout(5, lambda: int(input('What is the sum of 2 and 3?\n')))
print(ans)
except FunctionTimedOut:
print(5)

func_timeout returns the value of the method in its argument, the question() function in this case. It also allows for other arguments that are needed for the function (see documentation). If the set time elapses (5 secs here) it raises a TimedOutException and runs the code in the except block.

from threading import Thread
import time




def get_input():
while True:
print(input('> '))




t1 = Thread(target=get_input)
t1.setDaemon(True)
t1.start()
time.sleep(3)
print('program exceeds')

Well just simply set a new Daemon thread, and set a sleep time that whatever you want for timeout. I think that is easy to catch up XD

This is a Python 3.8+ (although it can be adapted to Python 3.6+) cross-platform approach that only uses threading (so no multiprocessing or calls to shell utilities). It is intended for running scripts from the command-line and isn't very suited for dynamical use.

You can wrap the builtin input function as follows. In this case I'm redefining the built-in name input as the wrapper, since this implementation requires all calls to input to be routed through this. (Disclaimer: that's why it's probably not a very good idea, just a different one, for fun.)

import atexit
import builtins
import queue
import threading




def _make_input_func():
prompt_queue = queue.Queue(maxsize=1)
input_queue = queue.Queue(maxsize=1)


def get_input():
while (prompt := prompt_queue.get()) != GeneratorExit:
inp = builtins.input(prompt)
input_queue.put(inp)
prompt_queue.task_done()


input_thread = threading.Thread(target=get_input, daemon=True)


last_call_timed_out = False


def input_func(prompt=None, timeout=None):
"""Mimics :function:`builtins.input`, with an optional timeout


:param prompt: string to pass to builtins.input
:param timeout: how long to wait for input in seconds; None means indefinitely


:return: the received input if not timed out, otherwise None
"""
nonlocal last_call_timed_out


if not last_call_timed_out:
prompt_queue.put(prompt, block=False)
else:
print(prompt, end='', flush=True)


try:
result = input_queue.get(timeout=timeout)
last_call_timed_out = False
return result
except queue.Empty:
print(flush=True) # optional: end prompt line if no input received
last_call_timed_out = True
return None




input_thread.start()
return input_func




input = _make_input_func()
del _make_input_func

(I've defined the setup in the one-use-only _make_input_func to hide input's "static" variables in its closure, in order to avoid polluting the global namespace.)

The idea here is to make a separate thread which handles any and all calls to builtins.input, and make the input wrapper manage the timeout. Since a call to builtins.input always blocks until there is input, when the timeout is over, the special thread is still waiting for input, but the input wrapper returns (with None). At the next call, if the last call timed out, it doesn't need to call builtins.input again (since the input thread has already been waiting for input), it just prints the prompt, and then waits for said thread to return some input, as always.

Having defined the above, try running the following script:

import time


if __name__ == '__main__':
timeout = 2
start_t = time.monotonic()
if (inp := input(f"Enter something (you have {timeout} seconds): ", timeout)) is not None:
print("Received some input:", repr(inp))
else:
end_t = time.monotonic()
print(f"Timed out after {end_t - start_t} seconds")


inp = input("Enter something else (I'll wait this time): ")
print("Received some input:", repr(inp))
    

input(f"Last chance to say something (you have {timeout} seconds): ", timeout)

Some of the answers require to press the Enter key when the timeout occurs to continue running your code. Others seem to be convoluted, and to boot, still require to press the Enter key after timeout.

I found the answer in another thread, which works beautifully, but there's a caveat that I found. I decided to place my code in a class for portability.

Note

I had to use keyboard to inject the Enter key press, since I had another input() statement in my code. For some reason, the subsequent input() statement wouldn't appear unless I pressed the Enter key.

import threading
import keyboard    # https://github.com/boppreh/keyboard


class Utilities:


# Class variable
response = None


@classmethod
def user_input(cls, timeout):


def question():
cls.response = input("Enter something: ")


t = threading.Thread(target=question)
# Daemon property allows the target function to terminate after timeout
t.daemon = True
t.start()
t.join(timeout)


if cls.response:
# Do something
else:
# Do something else
# Optional.  Use if you have other input() statements in your code
keyboard.send("enter")

Usage

Utilities.user_input(3)

This was made with Python 3.8.3 on Windows 10.

This is the code I've written. Using multiprocessing, we can timeout input.

from multiprocessing import Queue, Process
from queue import Empty

self.message: str = message




class Terminal:


@staticmethod
def input_with_timeout(message: str = '', timeout: int = 60) -> Tuple[Optional[str], Optional[Exception]]:
queue = Queue()
err: Optional[Exception] = None
user_input: Optional[str] = None
input_thread = Process(target=Terminal._input_async, args=(queue, message), daemon=True)
input_thread.start()
try:
user_input = queue.get(timeout=timeout)
except Empty:
input_thread.terminate()
err = ProcessTimedOutException(f'process timed out')
return user_input, err

def _input_async(queue, message: str = ''):

I had the same problem and solved it with keyboard and kthread. As soon as you press enter, the input field disappears. This was the most important thing for me, but I couldn't make it work with other approaches.

In November 2022, there's a project for Python 3 by werecatf in the pypi repository called pytimedinput. It works fine on my Windows 10 system. You can install it with pip like this:

C:\Users\User> pip install pytimedinput

Here's an example of usage:

from pytimedinput import timedInput
userText, timedOut = timedInput("Enter something: ", timeout=5)
if(timedOut):
print("Timed out when waiting for input.")
print(f"User-input so far: '{userText}'")
else:
print(f"User-input: '{userText}'")

键盘输入有超时吗？

Modified iperov answer that works for me (python3 win10 2019-12-09)
