在python中长按键盘按下监听器

Question

我想制作程序，以便在按下某个键之前它会重复执行特定事件，并且当它被释放时它不会做任何事情我无法实现相同的目标，我使用了 pynput 和键盘库但不知道如何完成这项工作，请帮忙

Answer 1

As you mentioned you have to download pynput in order to use it.

on_press function works as you hold the any key on_release key works when you release the key

from pynput.keyboard import Key, Listener

def on_press(key):
    a=5
    b=3
    print(a+b)

def on_release(key):
    if key == Key.esc:
        return False


with Listener(on_press=on_press,on_release=on_release) as listener:
    listener.join()
