You could use timer:

from threading import Timer

from pynput.keyboard import Listener


def on_press(key):
    print(key)


with Listener(on_press=on_press) as l:
    Timer(5, l.stop).start()
    l.join()
    print('5 seconds passed')

How could someone stop and start the stream? For instance say you need to get the keyboard's buttons every two minutes – Devilhorn Jan 08 '21 at 14:13

Just move the code into function and call it whenever needed. – makozaki Jan 10 '21 at 08:38

import time

from pynput.keyboard import Listener
from threading import Thread


def on_press(key):
    print(f"Key pressed: {key}")


with Listener(on_press=on_press) as ls:
    def time_out(period_sec: int):
        time.sleep(period_sec)  # Listen to keyboard for period_sec seconds
        ls.stop()

    Thread(target=time_out, args=(5.0,)).start()
    ls.join()
