enviar pulsaciones de teclas ejemplo de código de Python

Ejemplo 1: Pulse teclas en 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")

Ejemplo 2: tipo Python en el teclado

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('@@','[email protected]')# Block forever, like `while True`.
keyboard.wait()
