Which is the easiest way to simulate keyboard and mouse on Python?

I need to do some macros and I wanna know what is the most recommended way to do it.

So, I need to write somethings and click some places with it and I need to emulate the TAB key to.开发者_JAVA百科

I do automated testing stuff in Python. I tend to use the following:

I do not always (almost never) simulate key presses and mouse movement. I usually use COM to set values of windows objects and call their .click() methods.

You can send keypress signals with this:

import win32com.client

shell = win32com.client.Dispatch("WScript.Shell")
shell.SendKeys("^a") # CTRL+A may "select all" depending on which window's focused
shell.SendKeys("{DELETE}") # Delete selected text?  Depends on context. :P
shell.SendKeys("{TAB}") #Press tab... to change focus or whatever

This is all in Windows. If you're in another environment, I have no clue.

Maybe you are looking for Sendkeys?

SendKeys is a Python module for Windows that can send one or more keystrokes or keystroke combinations to the active window.

it seems it is windows only

Also you have pywinauto (copied from my SO answer)

pywinauto is a set of open-source (LGPL) modules for using Python as a GUI automation 'driver' for Windows NT based Operating Systems (NT/W2K/XP).

and example from the web page

> from pywinauto import application
> app = application.Application.start("notepad.exe")
> app.notepad.TypeKeys("%FX")
> app.Notepad.MenuSelect("File->SaveAs")
> app.SaveAs.ComboBox5.Select("UTF-8")
> app.SaveAs.edit1.SetText("Example-utf8.txt")
> app.SaveAs.Save.Click()

pyautogui is a great package to send keys and automate several keyboard / mouse related tasks. Check out Controlling the Keyboard and Mouse with GUI Automation and PyAutoGUI’s documentation.

You can use PyAutoGUI library for Python which works on Windows, macOS, and Linux.

Mouse

Here is a simple code to move the mouse to the middle of the screen:

import pyautogui
screenWidth, screenHeight = pyautogui.size()
pyautogui.moveTo(screenWidth / 2, screenHeight / 2)

Keyboard

Example:

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

Two other options are:

• pynput - https://pypi.org/project/pynput/ - which is for Windows (tested), Linux and MacOS- docs are at https://pynput.readthedocs.io/en/latest/
• PyDirectInput - https://pypi.org/project/PyDirectInput/ - which is for Windows only and can be used with (or without) PyAutoGUI

Warning - if you are wanting to use keyboard control for games, then pynput doesn't always work - e.g. it works for Valheim, but not for the Witcher 3 - which is where PyDirectInput will work instead. I also tested PyDirectInput and it works for Half life 2 (as a test of an older game).

Tip - You will likely need to reduce (don't remove for games) the delay between character typing - use pydirectinput.PAUSE = 0.05

As an example, here is a function that allows virtual keyboard typing - currently only tested on Windows:

from pynput import keyboard
try:
    import pydirectinput
    pydirectinput.PAUSE = 0.05
except ImportError as err:
    pydirectinput = False
    print("pydirectinput not found:")

def write_char(ch):
    upper = ch.isupper()
    if pydirectinput and pydirectinput.KEYBOARD_MAPPING.get(ch.lower(), False):
        if upper:
            pydirectinput.keyDown('shift')
            print('^')
        pydirectinput.write(ch.lower(), interval=0.0)
        print(ch)
        if upper:
            pydirectinput.keyUp('shift')
    else:
        keyboard.Controller().type(ch)

This allows a string to be sent in, with upper case alphabetic characters handled through pydirectinput. When characters don't simply map, the function falls back to using pynput. Note that PyAutoGUI also can't handled some shifted characters - such as the £ symbol, etc.
