Keyboard module in Python

Python provides a library named keyboard which is used to get full control of the keyboard. It's a small Python library which can hook global events, register hotkeys, simulate key presses and much more.

• It helps to enter keys, record the keyboard activities and block the keys until a specified key is entered and simulate the keys.
• It captures all keys, even onscreen keyboard events are also captured.
• Keyboard module supports complex hotkeys.
• Using this module we can listen and send keyboard events.
• It works on both windows and linux operating system.

Installation:

To install the keyboard module, run the following command:

pip install keyboard

Examples of Keyboard Module

Example 1: Simulating Key Presses and Blocking Keys

This code demonstrates how to simulate key presses and block the execution until a specific key is pressed using the keyboard module.

import keyboard

keyboard.write("GEEKS FOR GEEKS\n")

keyboard.press_and_release('shift + r, shift + k, \n')
keyboard.press_and_release('R, K')

keyboard.wait('Ctrl')

Output:

GEEKS FOR GEEKS 
RK
rk

Explanation:

• keyboard.write() writes the text "GEEKS FOR GEEKS" to the output.
• keyboard.press_and_release() simulates pressing and releasing the 'Shift + R', 'Shift + K', and 'Enter' keys.
• keyboard.wait() pauses the program execution and waits until the 'Ctrl' key is pressed to proceed.

Example 2: Using Hotkeys with Keyboard Module

This code shows how to use hotkeys with the keyboard module to trigger actions when specific keys or key combinations are pressed.

import keyboard 

keyboard.add_hotkey('a', lambda: keyboard.write('Geek')) 
keyboard.add_hotkey('ctrl + shift + a', print, args =('you entered', 'hotkey')) 

keyboard.wait('esc') 

Output

aGeek
you entered hotkey

Explanation:

• keyboard.add_hotkey() assigns the action of writing "Geek" when the 'a' key is pressed.
• A second hotkey (ctrl + shift + a) prints a message when pressed.
• keyboard.wait('esc') pauses the program until the 'Esc' key is pressed, terminating the program.

Example 3: Recording and Playing Key Events

This code demonstrates how to record and replay key presses using the keyboard module.

import keyboard

rk = keyboard.record(until ='Esc')

keyboard.play(rk, speed_factor = 1)

Output

Explanation:

• keyboard.record() records all key presses until the 'Esc' key is pressed.
• keyboard.play() replays the recorded key events at normal speed (speed_factor = 1).
