对于那些在窗户上努力寻找可行答案的人，我的是：pynput

from pynput.keyboard import Key, Listener

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

上面的功能将打印你按下的任何键，并在你释放“ esc”键时开始执行操作。键盘文档在这里用于更多变化的用法。

马库斯·冯·布罗迪（Markus von Broady）强调了一个潜在的问题，即：这个答案并不需要你在当前窗口中激活此脚本，Windows的解决方案是：

from win32gui import GetWindowText, GetForegroundWindow
current_window = (GetWindowText(GetForegroundWindow()))
desired_window_name = "Stopwatch" #Whatever the name of your window should be

#Infinite loops are dangerous.
while True: #Don't rely on this line of code too much and make sure to adapt this to your project.
    if current_window == desired_window_name:

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