模拟蟒蛇物理按键，在不提高LowLevelKeyHookInjected（0x10），以标志

Question

我试图模拟在python物理按键（即F12），而无需在Windows中提高LowLevelKeyHookInjected（0x10），以标志。这样做的目的是为了触发过滤掉模拟键盘按压程序的操作。该程序是一个辅助技术提供了一种用于控制OS备用访问方法。

我已经尝试了多种选择，包括的SendKeys，pyauotogui，pynput，CTYPE，等...

如果我身体按下F12，我可以触发相应的动作，但是，模拟F12请使用上面的方法都不起作用通过Python释放。下面是我所尝试过的例子：

import pynput.keyboard import Key, Controller
import time
Keyboard = Controller()
keyboard.press(Key.f12)
time.sleep(.05)
keyboard.release(Key.f12)

所以，它只是模拟F12按键，等待0.05秒，然后释放键。

我在Windows上运行的Python 3.6.6

感谢您对您的帮助提前！

这是我用来当我前几天有同样的问题。它有点乱，但它能够完成任务。 :)

F12()

只要使用F12（）来模拟F12键。

如果你想模仿其他键，以及你可以更改是说0x7B在F12功能，其他的东西（看在msdn.microsoft.com/en-us/library/dd375731找一下键有什么样的价值）。为了模拟字母，以及这可能有助于快速转换：

    keyCode = keyCodeMap[c[0]]
    return keyCode
