Python has a keyboard module with many features. Install it, perhaps with this command:
pip3 install keyboard
Then use it in code like:
import keyboard # using module keyboard
while True: # making a loop
try: # used try so that if user pressed other than the given key error will not be shown
if keyboard.is_pressed('q'): # if key 'q' is pressed
print('You Pressed A Key!')
break # finishing the loop
except:
break # if user pressed a key other than the given key the loop will break

For those who are on windows and were struggling to find an working answer here's mine: pynput.
Here is the pynput official "Monitoring the keyboard" source code example:
from pynput.keyboard import Key, Listener
def on_press(key):
print('{0} pressed'.format(
key))
def on_release(key):
print('{0} release'.format(
key))
if key == Key.esc:
# Stop listener
return False
# Collect events until released
with Listener(
on_press=on_press,
on_release=on_release) as listener:
listener.join()
The function above will print whichever key you are pressing plus start an action as you release the 'esc' key. The keyboard documentation is here for a more variated usage.
Markus von Broady highlighted a potential issue that is: This answer doesn't require you being in the current window to this script be activated, a solution to windows would be:
from win32gui import GetWindowText, GetForegroundWindow
current_window = (GetWindowText(GetForegroundWindow()))
desired_window_name = "Stopwatch" #Whatever the name of your window should be
#Infinite loops are dangerous.
while True: #Don't rely on this line of code too much and make sure to adapt this to your project.
if current_window == desired_window_name:
with Listener(
on_press=on_press,
on_release=on_release) as listener:
listener.join()
Hi, i want to simulate key presses (and shortcuts) in Python on Linux. I have already looked into pynput, and while it works, it is not global. what i am trying to do is as follows: i am using kde plasma as a desktop environment, and so in kde plasma settings, i made a shortcut (ctrl + a) that triggers the audio applet. so when i press that shortcut, the audio applet will open up. now what i want to achieve is that when a specific condition happens in my program, i open the applet.
from pynput.keyboard import Key, Controller
keyboard = Controller()
key = "a"
key2 = Key.ctrl
keyboard.press(key)
keyboard.press(key2)
keyboard.release(key)
keyboard.release(key2)
and while it works, but it is not global, and what i mean by this is that when i run this script i see "a" in the terminal as if i pressed it in the terminal, and the applet does not open up.
so any help on how can i achieve this ?
EDIT: i found a so much easier solution that works like a charm. There is a linux package called xdotool that stimulates mouse and keyboard stuff. So with this simple command xdotool key ctrl+a . It works perfectly. So i would just use an os.system and execute this.

Install the pywin32 extensions. Then you can do the following:
import win32com.client as comclt
wsh= comclt.Dispatch("WScript.Shell")
wsh.AppActivate("Notepad") # select another application
wsh.SendKeys("a") # send the keys you want
Search for documentation of the WScript.Shell object (I believe installed by default in all Windows XP installations). You can start here, perhaps.
EDIT: Sending F11
import win32com.client as comctl
wsh = comctl.Dispatch("WScript.Shell")
# Google Chrome window title
wsh.AppActivate("icanhazip.com")
wsh.SendKeys("{F11}")
You could also use PyAutoGui to send a virtual key presses.
Here's the documentation: https://pyautogui.readthedocs.org/en/latest/
import pyautogui
pyautogui.press('Any key combination')
You can also send keys like the shift key or enter key with:
import pyautogui
pyautogui.press('shift')
Pyautogui can also send straight text like so:
import pyautogui
pyautogui.typewrite('any text you want to type')
As for pressing the "A" key 1000 times, it would look something like this:
import pyautogui
for i in range(999):
pyautogui.press("a")
alt-tab or other tasks that require more than one key to be pressed at the same time:
import pyautogui
# Holds down the alt key
pyautogui.keyDown("alt")
# Presses the tab key once
pyautogui.press("tab")
# Lets go of the alt key
pyautogui.keyUp("alt")
I have a program which takes user input and outputs an answer. Now, I'd like to make it so that when the user presses a certain key, it exits the program. But how can you make it so that the program tries to detect that exit keypress at all times? Even when its looking for a user input?
I am only able to do one step at a time, like user input/output, then exit, or I can put exit first but that will just exit before anything happens
Thanks in advance!
