StopIteration during keyboard.write
On Fedora 28 with Python 3.6.6 I get the following problem:
>>> text = "TESTAA"
>>> keyboard.write(text)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/some/path/venv/lib/python3.6/site-packages/keyboard/__init__.py", line 852, in write

StopIteration
>>> TEST
Hi! I have exactly the same problem on Ubuntu 18.04, however I can use keyboard from pynput module for the same purposes, here is an example:
from pynput.keyboard import Controller
keyboard=Controller()
keyboard.type('TESTAA')
For doing so you need to download the pynput module, which can be downloaded from the terminal via pip with: pip install pynput
There is also a complete tutorial about simulating keypresses with pynput: https://nitratine.net/simulate-keypresses-in-python/

Hi! I can use keyboard from pynput module , but i had the save errors with @exploide !
I haven't tried yet using another module, but I have the same error
I wrote one for loop and it worked, I had to run it about 12 times to fill some stuff, all was fine I wrote another different for loop and I got iteration error
I'm on Ubuntu 18.04, but I believe I had similar error some time ago on Win10
Me too, same issue on below platforms:
4.18.0-kali3-amd64 #1 SMP Debian 4.18.20-2kali2 (2018-11-30) x86_64 GNU/Linux
4.4.0-142-generic #168-Ubuntu SMP Wed Jan 16 21:00:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Same here, ubuntu 18.10

I got a bit more info on this.
This is my _nixkeyboard.py:from_name.
I'm not sure why but it's missing a lot of characters. If I keyboard.write() characters from this table it works fine.

Just ran into this issue today while trying to use keyboard.write with a string with capital letters in it. We could only get it to work by using a lowercase string:
# Doesn't work
keyboard.write("AAAAA")
# Does work
keyboard.write("aaaaa")
For our use case, capitalization is not important, so we're just lowercasing our strings before we write them.
Knowing this, it seems like you'd have to use other methods to get proper capitalization in your strings (some combination of keyboard.press and keyboard.release could maybe work). It also looks like this example from the README
keyboard.write('The quick brown fox jumps over the lazy dog.')
doesn't work (at least on Linux).
Issue still prevalent on Linux, symbols and capital letters will throw "stopiteration"
Same issue on Centos 7 machine... script is simple
import keyboard keyboard.write("Python Programming is kinda cool I should say!", delay=0.3) keyboard.send('windows+l')
Steps to repro:
$ sudo python3 test_keyboard.py
Traceback (most recent call last):
File "test_keyboard.py", line 3, in
I've done research in SO but nothing... this appears the only place and the issue is Open.
If someone knows an alternative to the "keyboard" module that would be fantastic!
I am aware that something like this could be used(windows example):
import os os.system('rundll32.exe user32.dll,LockWorkStation')
However something more high level that can work on most machines would be best.
same thing happens here. i only get that error message when i am trying on linux. it works with no error in windows
I have the same problem on Ubuntu 18.04.4. I did a little digging and problem comes from "dumpkeys --keys-only". It's used to get the keys from the system and on my system a few of the capital letters are missing.
Use dumpkeys --keys-only | grep ^keycode to check which characters are affected.
I have an issue in Ubuntu-20.04 while using pynput module Code:
from pynput.keyboard import Controller
import time
keyboard = Controller()
time.sleep(2)
keyboard.type("hello world")
Output:
/usr/bin/python3.8 /home/<user>/PycharmProjects/Bots/bot.py
Process finished with exit code 0
and it printed : h wor
I pulled it from pip today and it still has this error on Linux. the pynput example worked, though, so I think I'll go with that.
For all of those helpless internet wanderers, the issue is this: it doesn't do uppercase letters because keyboards don't have them. That is to say, there's no "A" key, there's just an "a" and a "shift" key. Per the documentation, you're supposed to do something like:
keyboard.write("Baba booey.", exact=True)
which will force it to just send the string as Unicode. This actually worked, when I did it a few days ago -- but it's not working now, for reasons I can't understand, and all searches I've tried have landed me in sad little threads like this with people just as flummoxed as me.
Using the exact=True param as mentioned above didn't solve my issue.
As a workaround I send each char of a string separately and wrap it in a try except:
for char in 'poespoespSSSSoes!!POESPOESPOES!poespoespoes':
if char.isupper() or not char.isalpha():
keyboard.press_and_release(f'shift+{char.lower()}')
else:
try:
keyboard.press(char)
except Exception as err:
print(err)
try:
keyboard.release(char)
except Exception as err:
print(err)
This is the error when trying to press a capital char:
Traceback (most recent call last):

raise ValueError('Key {} is not mapped to any known key.'.format(repr(key)), e)
ValueError: ("Key 'S' is not mapped to any known key.", None)
edit: using keyboard.press with special keys like ! ain't working on wayland using sway, but keyboard.press_and_release('shift+1') does produce ! so I had to create a map for each special key and go from there.
edit: I ended up sending text to the clipboard and pasting it instead of pressing each character individually xD
Issue is still reproducible (Standard Manjaro + Python 3.10). Workaround for that problem could be to use caps lock button:
keyboard.send("capslock")
keyboard.write("text")
keyboard.send("capslock")
