Change keyboard locks in Python
提问by Lucas Jones
Is there any way, in Python, to programmatically changethe CAPS LOCK/NUM LOCK/SCROLL LOCK states?
在 Python 中，有什么方法可以以编程方式更改CAPS LOCK/NUM LOCK/SCROLL LOCK 状态？
This isn't really a joke question - more like a real question for a joke program. I intend to use it for making the lights do funny things...
这不是一个真正的笑话问题 - 更像是一个真正的笑话程序问题。我打算用它来让灯光做一些有趣的事情......

If you're using windows you can use SendKeysfor this I believe.
如果您使用的是 Windows ，我相信您可以为此使用SendKeys。

import SendKeys
SendKeys.SendKeys("""
{CAPSLOCK}
{SCROLLOCK}
{NUMLOCK}
""")

On Linux here's a Python program to blink all the keyboard LEDs on and off:
在 Linux 上，这是一个 Python 程序，用于打开和关闭所有键盘 LED：
import fcntl
import os
import time
KDSETLED = 0x4B32
SCR_LED = 0x01
NUM_LED = 0x02
CAP_LED = 0x04
console_fd = os.open('/dev/console', os.O_NOCTTY)
all_on = SCR_LED | NUM_LED | CAP_LED
all_off = 0
while 1:
fcntl.ioctl(console_fd, KDSETLED, all_on)
time.sleep(1)
fcntl.ioctl(console_fd, KDSETLED, all_off)
time.sleep(1)

To set CAPS LOCK to a specific value using SendKeys it is important to first detect the state of CAPS LOCK. Here's how to do that in python (under windows):
要使用 SendKeys 将 CAPS LOCK 设置为特定值，首先检测 CAPS LOCK 的状态很重要。以下是在 python 中（在 Windows 下）中执行此操作的方法：
import win32api,win32con
def IsCapsLockOn():
# return 1 if CAPSLOCK is ON
return win32api.GetKeyState(win32con.VK_CAPITAL)

#https://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx
import win32com.client as comclt
wsh= comclt.Dispatch("WScript.Shell")
wsh.SendKeys("abc") #types out abc directly into wherever you have your cursor (ex: right into this editor itself!)
wsh.SendKeys("{NUMLOCK}{CAPSLOCK}{SCROLLLOCK}") #toggles the state of NumLock, CapsLock, and ScrollLock; remove whichever one you don't want to toggle

Also, pay careful attention to Uri's answer about how to read the CapsLock state. To set an LED state specifically to true or false, you can't just blindly toggle, you have to know what the current state is first. He shows you how to read the CapsLock state. Here's how to read all 3 LED states:
另外，请注意 Uri 关于如何读取 CapsLock 状态的回答。要将 LED 状态专门设置为 true 或 false，您不能只是盲目地切换，您必须首先知道当前状态是什么。他向您展示了如何读取 CapsLock 状态。以下是读取所有 3 个 LED 状态的方法：

import win32api,win32con
def isCapsLockOn():
"return 1 if CapsLock is ON"
return win32api.GetKeyState(win32con.VK_CAPITAL)
def isNumLockOn():
"return 1 if NumLock is ON"
return win32api.GetKeyState(win32con.VK_NUMLOCK)
def isScrollLockOn():
"return 1 if ScrollLock is ON"
return win32api.GetKeyState(win32con.VK_SCROLL)
print("IsCapsLockOn = ", IsCapsLockOn())
print("isNumLockOn = ", isNumLockOn())
print("isScrollLockOn = ", isScrollLockOn())

Don't know all the details yet, but start here: Change keyboard locks in Python.
还不知道所有细节，但从这里开始：在 Python 中更改键盘锁。
Is there a generic Python module for any OS?
是否有适用于任何操作系统的通用 Python 模块？

Probably of no use to the OP but worth sharing as someone might be looking for the answer as i was but could not find the solution without using third party modules. This is what i did to turn the caps lock on
可能对 OP 没有用，但值得分享，因为有人可能会像我一样寻找答案，但如果不使用第三方模块就找不到解决方案。这就是我打开大写锁定所做的工作
import ctypes
def turn_capslock():
dll = ctypes.WinDLL('User32.dll')
VK_CAPITAL = 0X14
if not dll.GetKeyState(VK_CAPITAL):
dll.keybd_event(VK_CAPITAL, 0X3a, 0X1, 0)
dll.keybd_event(VK_CAPITAL, 0X3a, 0X3, 0)
return dll.GetKeyState(VK_CAPITAL)
print(turn_capslock())
