If you're using windows you can use <a href="https://pypi.python.org/pypi/SendKeys/" rel="nofollow noreferrer">SendKeys</a> for this I believe.

On Linux here's a Python program to blink all the keyboard LEDs on and off:

<pre><code>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)
</code></pre>

blocks|key|1837477|text|要使用SendKeys将CAPS+LOCK设置为特定值，重要的是首先要检测CAPS+LOCK的状态。下面是如何在python中(在windows下)做到这一点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1837478|import+win32api,win32con

def+IsCapsLockOn():
++++#+return+1+if+CAPSLOCK+is+ON

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):

<pre><code>import win32api,win32con

def IsCapsLockOn():
 # return 1 if CAPSLOCK is ON
 return win32api.GetKeyState(win32con.VK_CAPITAL)
</code></pre>

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

<pre><code>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())
</code></pre>

blocks|key|1837585|text|使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1837586|from+win32api+import+GetKeyState

GetKeyState(VK_CAPITAL)|code-block|syntax|javascript|1837587|1+==+True+0+==+False|1837588|您也可以获得其他密钥，列表如下：https://docs.microsoft.com/en-au/windows/win32/inputdev/virtual-key-codes|offset|length|1837589|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.microsoft.com/en-au/windows/win32/inputdev/virtual-key-codes^0|0|0|0|G|21|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|X|8|@]|9|@$K|Y|L|Z|1|10]]|A|$]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|T]]]]

Use this:
<pre><code>from win32api import GetKeyState
from win32con import VK_CAPITAL

GetKeyState(VK_CAPITAL)

1 == True
0 == False

Is there any way, in Python, to programmatically change the CAPS LOCK/NUM LOCK/SCROLL LOCK states?

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...

Change keyboard locks in Python

在Python中，有没有办法以编程方式更改CAPS LOCK/NUM LOCK/SCROLL LOCK状态？这不是一个真正的笑话问题--更像是一个真正的笑话程序的问题。我打算用它来让灯光做一些有趣的事情。
