pynput似乎不能处理caps lock键

Question

在windows10、python3.7中使用pynput，返回的字符代码反映了程序启动时caps lock键的状态。对该键的更改不会导致返回值的更改。你知道吗

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

with keyboard.Listener(on_release=on_release) as listener:
    listener.join()

当这是运行与大写锁定我得到：

'A' released
Key.caps_lock released
'A' released
Key.esc released
Aa
>>> 

所以大写锁定现在关闭了。我明白了

'a' released
Key.caps_lock released
'a' released
