Master Python Input Control: Using pynput to Automate Mouse and Keyboard

Overview

The pynput library allows you to control and monitor input devices in Python.

Modules

It provides two sub‑packages:

pynput.mouse : classes for controlling and monitoring the mouse or touchpad.

pynput.keyboard : classes for controlling and monitoring the keyboard.

Control Mouse

Import the mouse module from pynput and use its Controller class to move the cursor or click buttons.

Monitor Mouse Events

Use pynput.mouse.Listener to listen for mouse events. The listener runs in a separate thread; callbacks execute in that thread. Call stop(), raise StopException, or return False from a callback to stop listening.

Control Keyboard

Import the keyboard module and use pynput.keyboard.Controller to send keystrokes.

Monitor Keyboard Events

Use pynput.keyboard.Listener to listen for keyboard events. The listener also runs in its own thread. Stopping works the same way as for the mouse listener. The callback receives a Key instance; printable keys are provided as KeyCode objects, and unknown keys return None.
