Python模拟keydown
search几个小时后，我想知道是否有可能模拟keydown键盘上的按下。 例如，我希望我的程序按住“x”键五秒钟，所以当我在记事本中运行它时，会看起来像这样： xxxxxxxxxxxxx 。 我在网上尝试了不同的代码，到目前为止我能find的最好的东西是：
import ctypes import time user32 = ctypes.windll.user32 inputhex = raw_input("Please enter your desired key's code (HEX): ") keycode = int(inputhex, 16) time.sleep(1) #VOID keybd_event(BYTE bVk, BYTE bScan, DWORD dwFlags, PTR dwExtraInfo); user32.keybd_event(keycode,0,2,0) #is the code for KEYDOWN time.sleep(5) #user32.keybd_event(keycode,0,0,0) #is the code for KEYDUP[/code]
Sendkey模块不能解决我的问题，因为它只允许你发送一个按键，而不是一个保持键按下的事件。 我知道过去使用它，但我真的想知道这是否可能与python和如何。 PS我正在使用Python的窗户
这段代码应该让你开始。 ctypes被大量使用。 在底部，你会看到示例代码。

如果你使用的是Windows的Python，那么你很有可能拥有win32api模块，这个模块可以处理你的API。
>>> import win32api >>> import win32con >>> win32api.keybd_event(win32con.SHIFT_PRESSED, 0, win32con.KEYEVENTF_EXTENDEDKEY, 0) >>> HELLO
这有帮助吗？ （ps你应该尽可能安装IPython，这对于实验来说是非常有帮助的）
我知道这个问题真的很老，但我find了一个很好的库： PyUserInput 。 我不知道如何在Windows下载它（很久以前，我还没有下载Windows的库）。 在Linux中很容易，只需下载点（如果你没有）： sudo apt-get install pip ，然后sudo pip install pyuserinput 。 然后代码非常简单：
#imports the library from pykeyboard import PyKeyboard #import the sleep function from time import sleep #initialize the keyboard simulator keyboard = PyKeyboard() #presses the key keyboard.press_key('x') #waits five seconds before releasing the key sleep(5) #releases the key keyboard.release_key('x')
我已经修改了Noctis的答案来处理Unicode字符。
