If key_pressed("\x00\x48"): # Up arrow key on Windows.įind out special keys using print_key(): > print_key() You can also check for a specific key: while True: You can use key_pressed() inside a while loop: while True: Useful for ignoring multiple key-presses. Post_flush: If True (default), flush the input buffer after the key wasįound. Useful in case you wish to ignore previously pressed keys. Pre_flush: If True, flush the input buffer before waiting for input. """Wait for a specific key to be pressed. Useful for debugging and figuring out keys. If None, any key will do.įlush: If True (default), flush the input buffer after the key was found.īoolean stating whether a key was pressed. """Return True if the specified key has been pressed _MAX_ESCAPE_SEQUENCE_LENGTH = len(_ESCAPE_SEQUENCES) _termios.tcsetattr(fd, _termios.TCSADRAIN, old_settings) Select as _select, functools as _functoolsįrozenset(("\x1b\x5b", _set_terminal_raw(): Import sys as _sys, tty as _tty, termios as _termios, \ _set_terminal_raw = _contextlib.nullcontext # Length 0 sequences, length 1 sequences. Here is a cross-platform solution, both blocking and non-blocking, not requiring any external libraries: import contextlib as _contextlib If you want the full source code of the program you can see it or download it from GitHub Print(" You pressed:'", kp "', that's not the secret key(s)\n") Print(bk "CONGRATULATIONS YOU PRESSED THE SECRET KEYS!\a" bk) # \x8a is CTRL F12, that's the secret key. # If user pressed the secret key, the game ends. # Refactor the variable in case of multi press. # Get the key pressed by the user and check if he/she wins. The following is the main function of the game, that is detecting the keys pressed: import msvcrt I made this kind of game based on this post (using msvcr library and Python 3.7). keyboard will read keypresses from the whole OS.It records all keys pressed and released until you press the escape key or the one you've defined in until arg and returns a list of keyboard.KeyboardEvent elements. It will be using the function is_pressed but in an other way: import keyboard This method is sort of already answered by user8167727 but I disagree with the code they made. You can stop all hooks by running this line: keyboard.unhook_all() Once executed, it will run the function when the key is pressed. I used _ because the keyboard function returns the keyboard event to that function. Keyboard.on_press_key("p", lambda _:print("You pressed p")) Using the function on_press_key: import keyboard It will wait for you to press p and continue the code as it is pressed. This is gonna break the loop as the key p is pressed. Using the function read_key(): import keyboard You can install this module using pip install keyboard More things can be done with keyboard module. While True: #Don't rely on this line of code too much and make sure to adapt this to your project. 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, GetForegroundWindowĬurrent_window = (GetWindowText(GetForegroundWindow()))ĭesired_window_name = "Stopwatch" #Whatever the name of your window should be The keyboard documentation is here for a more variated usage. The function above will print whichever key you are pressing plus start an action as you release the 'esc' key. As shown in my video, we can also just call listener.stop() in one of the definitions due to the fact that that the listener is now in scope and is an instance os Listener.For those who are on windows and were struggling to find an working answer here's mine: pynput from pynput.keyboard import Key, Listener join() until the Listener is stopped.Īs stated here in the pynput docs on readthedocs.io, we can call anywhere in the script to stop the thread or return False from a callback to stop the listener. Just as a quick note, the Listener class is a thread which means as soon as it has joined to the main thread no code will be executed after the. The actual location of this file will be in the current working directory of where you run the script from The Listener Thread ![]()
