Controlling your keyboard and mouse in Python using pyautogui

While recently looking to program an AI to play a (very simple) video game, I needed a way to control the game automatically and to log any keystrokes used so I could train a convolutional neural network to predict which action to take based on what it could see on screen.

I came across pyautogui, a Python package which can simulate moving the mouse, clicking the mouse, dragging with the mouse, pressing keys, pressing and holding keys, and pressing keyboard hotkey combinations.

I’ve included a couple of examples which showcase some interesting use-cases. Take a look at the homepage for this package here for a more comprehensive overview of what can be achieved with this package.

Example 1 – Drawing

Open MS Paint (or another drawing program) open and ensure the drawing space is taking up most of the screen

Run the below code in Python

Important: You will have 3 seconds to switch the window from Python to Paint. Once in Paint - hover your cursor where you want the drawing to start

import pyautogui

import time

#code will sleep for 3 seconds so we can switch over to MS Paint


distance = 200

while distance > 0:

pyautogui.dragRel(distance, 0, duration=0.2) # move right

distance -= 5

pyautogui.dragRel(0, distance, duration=0.2) # move down

pyautogui.dragRel(-distance, 0, duration=0.2) # move left

distance -= 5

pyautogui.dragRel(0, -distance, duration=0.2) # move up

Example 2 – Opening Notepad and write a message



pyautogui.typewrite(['n','o','t','e','p','a','d','enter'], interval=0.25)

pyautogui.typewrite('Hello World, Pyautogui at your service...', interval=0.25)

This is a pretty noddy way to achieve this task, but it’s in interesting illustration of what pyautogui can do. As I mentioned above, do take a look here for the complete overview of the package!
