修复按键重复 Python

Question

我有一个等待按键并将它们记录在控制台中的脚本：from pynput.keyboard import Key, Listenerdef on_press(key):    print('{0} pressed'.format(        key))def on_release(key):    print('{0} release'.format(        key))    if key == Key.esc:        # Stop listener        return False# Collect events until releasedwith Listener(        on_press=on_press,        on_release=on_release) as listener:    listener.join()系统本身可以工作，但是，当按住某个键时，它会产生以下结果：Key.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressed如何使线程暂停，直到释放键？

Answer 1

我们可以使用一个集合来检查当前正在按下哪个键。

pressing_keys_set = set()

def on_press(key):

    if key not in pressing_keys_set:

        print('{0} pressed'.format(key))

        pressing_keys_set.add(key)

def on_release(key):

    print('{0} release'.format(key))

    pressing_keys_set.remove(key)

    if key == Key.esc:

        # Stop listener

        return False

# Collect events until released

with Listener(

    on_press=on_press,

    on_release=on_release) as listener:

    listener.join()

此代码必须帮助您

from pynput.keyboard import Key, Listener

is_released=False

def on_press(key):

    global is_released

    if is_released:

        print('{0} pressed'.format(key))

        is_released=False

def on_release(key):

    global is_released

    print('{0} release'.format( key))

    is_released=True

    if key == Key.esc:

        # Stop listener

        return False

# Collect events until released

with Listener(

        on_press=on_press,

        on_release=on_release) as listener:

    listener.join()
