How do I use the Python module "keyboardleds" to determine Caps Lock state?

1. I want my system to ascertain the state of Caps Lock (is it on or off) by inspecting the keyboard DIRECTLY. After much searching, I understand that this can be done in Python by using the module "keyboardleds". I'm not familiar with Python, **so my main request is, can you tell me how to use the module keyboardleds in a Python script, so that it tells me what the state of Caps Lock is?** The Python version on my system is 2.7.3rc2. 2. The information I've found about "keyboardleds", is too technical for me to understand. Also an example I found of how keyboardleds is used, uses complex python programming that I don't understand either. Also, the example I've looked at uses keyboardleds for one of its **other** purposes, not for the purpose I want (ie determining the state of Caps Lock). I don't even know what the "import" commands mean at the beginning of the example script, and whether I need all of them. **I would be most grateful if you could tell me what python commands I need to use, and what detailed contents I put in them.** 3. I just need the python script to give an exit status of zero (true) if Caps Lock is off, and an exit status of 1 (false) if Caps Lock is on. Say the python script is called "capslockstate". Then I'll use it in a bash script as follows: if capslockstate then else fi 4. SIGNIFICANT I BELIEVE: Regarding accessing the keyboard, the info I've found refers to using either /dev/console, /dev/input/event*, and /dev/input/by-path/*-event-kbd. On my system, all 3 of these exist. In the latter 2 cases, I've got the following on my system: /dev/input/event0 through to /dev/input/event9. /dev/input/by-path/platform-i8042-serio-0-event-kbd ### ie only ^this^ one item exists The "by-path" is the **actual** directory name. I believe that one of the above 2 "/dev/input/..." entities is what I need to use (as opposed to /dev/console), even though I don't understand the ins and outs of it. 5. Below are the websites where I found the information on keyboardleds: 1. The first site that put me onto using keyboardleds (with examples that are too complex for me): Alternative approaches for accessing keyboard LEDs in Linux with Python What particularly interested me on this site is the comment "the program [keyboardleds] accesses the keyboard DIRECTLY." 2. Official documentation I believe, on keyboardleds (too complex for me to understand): python-keyboardleds 0.3.3 documentation 3. The site of the author of keyboardleds: python-keyboardleds — Jakub Wilk's software
