Python：Linux 控制台中的按键/释放处理

  • 772

需要通过控制台来组织键盘的处理。你需要分配一个动作来按下按钮并按下它。例如，pygame 解决了一个类似的任务，它看起来像这样：

for events in pygame.event.get():
    if events.type == pygame.KEYDOWN:
        #проверяем конкретную клавишу...
    if events.type == pygame.KEYUP:
        #проверяем конкретную клавишу...

但在 pygame 中，捕获发生在创建的窗口中，而不是在控制台中。

    pynput模块允许您读取键盘和鼠标键的按下和“释放”，以及控制它们（即按下、移动等）：

    from pynput import keyboard

def on_press(key):
    try:
        print('alphanumeric key {0} pressed'.format(
            key.char))
    except AttributeError:
        print('special key {0} pressed'.format(
            key))

def on_release(key):
    print('{0} released'.format(
        key))
    if key == keyboard.Key.esc:
        # Stop listener
        return False

# Collect events until released
with keyboard.Listener(
        on_press=on_press,
        on_release=on_release) as listener:
    listener.join()

    在屏幕上显示结果：

    special key Key.up pressed
Key.up released
special key Key.down pressed
Key.down released
special key Key.right pressed
Key.right released
special key Key.left pressed
Key.left released
alphanumeric key a pressed
'a' released
special key Key.shift pressed
Key.shift released
special key Key.shift pressed
alphanumeric key d pressed
'd' released
Key.shift released
special key Key.alt_l pressed
special key Key.shift pressed
alphanumeric key a pressed
'a' released
Key.shift released
Key.alt_l released
special key Key.space pressed
Key.space released
special key Key.enter pressed
Key.enter released
special key Key.alt_l pressed
Key.alt_l released
