我一直在使用pynput。

Question

大家好，我是9岁的库尔特·李（Kurt Lee），我想问一下如何使用pynput键盘设法修复此音量栏。

from pynput.keyboard import Key, Listener
from ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume



def volume_controller(control):  #
    devices = AudioUtilities.GetSpeakers()
    interface = devices.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)
    volume = cast(interface, POINTER(IAudioEndpointVolume))
    vol = volume.SetMasterVolumeLevel(control, None)
    return vol

# Volume Bar
VolumeMax = "▁ ▂ ▃ ▄ ▅ ▆ █ 100%" + str(volume_controller(-0))
# Volume86 = "▁ ▂ ▃ ▄ ▅ ▆ 86%" + str(volume_controller(-2.3))
# Volume72 = "▁ ▂ ▃ ▄ ▅ 72%" + str(volume_controller(-5))
# Volume58 = "▁ ▂ ▃ ▄ 58%" + str(volume_controller(-8))
# Volume44 = "▁ ▂ ▃ 44%" + str(volume_controller(-12.2))
# Volume30 = "▁ ▂ 30%" + str(volume_controller(-17.9))
# Volume16 = "▁ 16%" + str(volume_controller(-26.5))
VolumeZero = "Muted" + str(volume_controller(-60))


def check_key(key):
    keyword = key
    if keyword is Key.up:
        print('UP')
        print(VolumeMax)

    elif keyword is Key.down:
        print("Down")
        VolumeZero


# Collect events until released
with Listener(on_press=check_key) as l:
    l.join()

我一直在修复一个星期时遇到困难，我非常需要帮助。例如，我目前的音量是100％，即最大音量，我想通过单击下降来将其降低到86％，然后下一个是将其提高到100％或更低至72％。
