Presskeys in python
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")
python type on keyboard
pip install keyboard import keyboard keyboard.press_and_release('shift+s, space') keyboard.write('The quick brown fox jumps over the lazy dog.') keyboard.add_hotkey('ctrl+shift+a', print, args=('triggered', 'hotkey')) # Press PAGE UP then PAGE DOWN to type "foobar". keyboard.add_hotkey('page up, page down', lambda: keyboard.write('foobar')) # Blocks until you press esc. keyboard.wait('esc') # Record events until 'esc' is pressed. recorded = keyboard.record(until='esc') # Then replay back at three times the speed. keyboard.play(recorded, speed_factor=3) # Type @@ then press space to replace with abbreviation. keyboard.add_abbreviation('@@', 'my.long.email@example.com') # Block forever, like `while True`. keyboard.wait()
