Autopy library:

• The autopy library is a Python library for automating user input. It provides an easy way to send keystrokes and mouse movements.

• In this code, the autopy.key.type_string() function is used to send the string "Hello, world!" as keystrokes. The wpm parameter specifies the typing speed in words per minute. By default, it is set to None, which means that the string is printed out as quickly as the operating system allows.

• The autopy.key.tap() function is used to tap a single key. In this code, it is used to press the Return key, the F1 key, and the left arrow key.

Pyautogui library:

• The pyautogui library is another Python library for automating user input. It provides a more comprehensive set of features than autopy, including the ability to control the mouse cursor, read the screen, and perform window management.

• In this code, the pyautogui.typewrite() function is used to send the string "Hello world!" as keystrokes. The interval parameter specifies the delay between each keystroke in seconds. By default, it is set to 0, which means that the string is printed out instantly.

• The pyautogui.press() function is used to press a single key. In this code, it is used to press the Enter key, the F1 key, and the left arrow key.

• The pyautogui.keyDown() and pyautogui.keyUp() functions are used to hold down a key and then release it. In this code, the Shift key is held down and then released.

• The pyautogui.hotkey() function is used to press a combination of keys. In this code, the Ctrl, Shift, and Esc keys are pressed together.

import autopy
autopy.key.type_string("Hello, world!") # Prints out "Hello, world!" as quickly as OS will allow.
autopy.key.type_string("Hello, world!", wpm=60) # Prints out "Hello, world!" at 60 WPM.
autopy.key.tap(autopy.key.Code.RETURN)
autopy.key.tap(autopy.key.Code.F1)
autopy.key.tap(autopy.key.Code.LEFT_ARROW)


>>> import pyautogui
>>> pyautogui.typewrite('Hello world!')                 # prints out "Hello world!" instantly
>>> pyautogui.typewrite('Hello world!', interval=0.25)  # prints out "Hello world!" with a quarter second delay after each character
>>> pyautogui.press('enter')  # press the Enter key
>>> pyautogui.press('f1')     # press the F1 key
>>> pyautogui.press('left')   # press the left arrow key
>>> pyautogui.keyDown('shift')  # hold down the shift key
>>> pyautogui.press('left')     # press the left arrow key
>>> pyautogui.keyUp('shift')    # release the shift key
>>> pyautogui.hotkey('ctrl', 'shift', 'esc')
