I want to create program that check if a is pressed. But for a lot of times, not only one time. I tried using for loop and function but I failed.
import keyboard
def lagun():
while True:
try:
if keyboard.is_pressed('a'):
print('you pressed a')
break
except:
break
Can anyone could tell me how to modify this code to check is a is pressed a lot of times?

import keyboard
import pygame
import mouse
import time
def press_X():
time.sleep(0.2)
keyboard.press('x')
time.sleep(0.6)
keyboard.release('x')
print('Command Executed - press_X')
#SA_R_X V_1.0
#------------------------------------------
while True:
try:
keyboard.add_hotkey('r', press_X)
time.sleep(0.5)
break
except:
keyboard.add_hotkey('r', press_X)
time.sleep(0.5)
break
the problem is the code cannot detect if 'r' is pressed when i am holding 'w' and/or 'space'... (well any key really)
I tried to use a try and except to handle a combination of any key + 'r'. But it did not work. All I need is for the code to be able to detect an 'r' input even if I am pressing/ holding another key at the same time. Then after this the code waits 0.2 seconds before holding down the 'x' key for 0.6 seconds and releasing. Any help is appreciated and it would be very helpful if you included a short explanation on where I went wrong and how you fixed it.
The documentation for this module can be found here. This is where all relevant information can be found.
The best way to do this, from my understanding, is to use an alternative function. If you want the program to continue to run, even though the key has not been pressed, then I suggest using the keyboard.on_press_key() function. This would mean that the rest of your program could still run, and your press_X() function could be run as a callback. Here is an example of how this code could be implemented.
import keyboard
import pygame
import mouse
import time
class App:
running = True
def press_X():
time.sleep(0.2)
keyboard.press('x')
time.sleep(0.6)
keyboard.release('x')
print('Command Executed - press_X')
App.running = False
#SA_R_X V_1.0
#------------------------------------------
keyboard.on_press_key('r', lambda x: press_X()) ## Adds an event listener for the r key
## This will stop execution if there is no code after this point
If you want it to stop the program and wait for the r key to be pressed, then you could use keyboard.wait(). This will basically pause your program until the key is pressed, after which your function would be run. For example, to replace the keyboard.on_press_key('r', lambda x: press_X()):
keyboard.wait('r')
press_X()
From my understanding, keyboard.add_hotkey() does not work in your situation because it is looking for an exact combination of keys being pressed, such as Ctrl+C, and will only go if only the keys in the hotkey are pressed.
I hope this helps, good luck!
I am making a program in python to detect what key is pressed and based on my keyboard it will make a decision.
I want to implement it using keyboard module in python.
I would do something like this,
import keyboard
while True:
if keyboard.read_key() == 'enter':
print('Enter is pressed)
if keyboard.read_key() == 'q':
print('Quitting the program)
break
if keyboard.read_key() == 's':
print('Skiping the things')
But it doesn't work. When I execute this program, I have to press s twice to execute the "s" block.
Also, I have a problem that is after the execution is finished, it writes all the keys in my command prompt is it possible to fix that?
As per Keyboard documentation:
Other applications, such as some games, may register hooks that swallow all key events. In this case keyboard will be unable to report events.
One way to solve your problem with keyboard module is keyboard.wait('key')
# Blocks until you press esc
keyboard.wait('esc')
Something work around is as below:
import keyboard
keyboard.wait('enter')
print('Enter is pressed')
keyboard.wait('q')
print('Quitting the program')
keyboard.wait('s')
print('Skiping the things')
As Far I Know There is only one efficient way to Detect user input weather it keybored or mouse input Which is library called pynput ......
from pynput.keyboard import Key , Listener , Controller
keyboard = Controller()
DoubleShot=False
shot=False
def on_press(key):
global DoubleShot
global shot
if Key.num_lock == key:
print("activate")
DoubleShot=True
if DoubleShot:
if Key.shift == key:
shot = not shot
if shot:
keyboard.press(Key.shift)
keyboard.release(Key.shift)
def on_release(key):
if key == Key.esc:
return False
with Listener(on_press=on_press , on_release=on_release) as listener:
listener.join()
i create this for a game to shoot multiple time on 'shift' clicked
code activate only when ' numlock ' clicked.....
Controller is for clicking any key you want
Note:
In My case infinity looping was a problem that's why shot variable is there to stop looping
How do I check if ANY key is pressed?
this is how I know to detect one key:
import keyboard # using module keyboard
while True: # making a loop
if keyboard.is_pressed('a'): # if key 'q' is pressed
print('You Pressed A Key!')
break # finishing the loop
How do I check if any key (not just letters) is pressed?
For example, if someone presses the spacebar it works, the same for numbers and function keys, etc.
while True:
# Wait for the next event.
event = keyboard.read_event()
if event.event_type == keyboard.KEY_DOWN:
print(event.name) # to check key name
Press any key and get the key name.
it can be done using the msvcrt module as the following:
import msvcrt
while True:
if msvcrt.kbhit():
key = msvcrt.getch()
break
or the keyboard, although i am not sure of how of a good practice this code is:
import keyboard
while True:
try:
print(keyboard.read_key())
break
except:
pass
if this is bad practice please informe me in the coments so i can mark it as unfavored
thankyou.
Correct solution in Windows is to use msvcrt
Please check thread here:
How to detect key presses?
I think somehow should be possible also with builtin input() command.
Have a nice day!
I have this relatively simple program that listens for mouse clicks and when the mouse button is held down prints "1"s. Unfortunately when I let go of the mouse it just keeps printing "1"s, even though there is an if statement which checks if the mouse is clicked and should stop the loop if it is not. I am using the pynput.mouse module for the mouse interaction.
Here is my code:
import time
from pynput.mouse import Listener
def clicked(x, y, button, pressed):
if pressed == True:
while button == button.left:
print("1")
time.sleep(1)
if pressed == False:
break
with Listener(on_click=clicked) as listener:
listener.join()
My theory is that once the loops starts it stops listening for mouse clicks, so it can never stop the loop. Would it be necessary to create a new thread for the loop? If yes, how would I do that?
Thanks!
Your current logic makes it impossible to get out of the loop, since pressed doesn't change within the loop. There is not a statement that checks if the mouse is clicked: your only if statements check whether the mouse was clicked when you entered the function. pressed doesn't change within the function.
Look at the critical logiic:
if pressed == True:
while ...
...
if pressed == False:
break
There is nothing in here to change the value of pressed; the first if guarantees that it's True anywhere within the loop.
Yes, you need to set up another listener that operates within the loop. You already know the building blocks: create a new one within the function and bind it to another operation that breaks the loop. For instance, you might "cheat" and have it reset pressed as a global variable.
You could also research how to do this in other answers, if you want an overall handler solution. keypress and keyrelease have been done often enough.
import pyautogui, random, time
import pynput
keys = ['w', 's', 'a', 'd']
def on_press(key):
p = True
if key == pynput.keyboard.Key.esc:
return False
else:
while p == True:
press = keys[random.randint(0,3)]
pyautogui.keyDown(press)
pyautogui.keyUp(press)
p = False
with pynput.keyboard.Listener(on_press=on_press) as L:
L.join()
a code like this will work instead of what you did.
BTW, that is just an example; feel free to visit my GitHub page: github.com/ironnicko
from time import sleep
alive = True
while alive == True:
print("You have awoken in a unknown land.")
sleep(2)
print("\nDo you go north, south, east or west?")
print("Press the up arrow to go north.")
print("Press the down arrow to go south.")
print("Press the left arrow to go west.")
print("Press the right arrow to go east.")
input(" ")
How do I get the user to press one of the arrow keys and have the program carry on without the need of pressing the enter key?
Thanks in advance!

You may look into a package like pynput for multiplatform support. Pynput implements mouse and keyboard listeners. This will also allow you to do WSAD movement in your RPG-like game.
For keyboard listeners, you can have a onpress/onrelease key. The help files will have some better examples.
from pynput import keyboard
def on_press(key):
try:
print('alphanumeric key {0} pressed'.format(
key.char))
except AttributeError:
print('special key {0} pressed'.format(
key))
def on_release(key):
print('{0} released'.format(
key))
if key == keyboard.Key.esc:
# Stop listener
return False
# Collect events until released
with keyboard.Listener(
on_press=on_press,
on_release=on_release) as listener:
listener.join()
If you want to use up/down/left/right (arrow keys) for movement, this may be the easiest least painful solution too.
You Could Make Options Like:
option = input('1/2/3/4:')
or:
Python has a keyboard module with many features. You Can Use It In Both Shell and Console.
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('up'): #if key 'up' is pressed.You can use right,left,up,down and others
print('You Pressed A Key!')
#your code to move up here.
break #finishing the loop
else:
pass
except:
break #if user pressed other than the given key the loop will break
You can set it to multiple Key Detection:
if keyboard.is_pressed('up') or keyboard.is_pressed('down') or keyboard.is_pressed('left') or keyboard.is_pressed('right'):
#then do this
You Can Also Do Something like:
if keyboard.is_pressed('up') and keyboard.is_pressed('down'):
#then do this

Thanks.
