Keyboard module in Python

The keyboard module in Python allows you to control and monitor keyboard events programmatically. It provides functionality for simulating keystrokes, detecting key presses, and creating keyboard shortcuts across different platforms.

Installation

Install the keyboard module using pip ?

pip install keyboard

Note: This module requires administrator/root privileges to work properly on most systems.

Key Features

• Cross-platform compatibility (Windows, macOS, Linux)
• Simulate keyboard input and key combinations
• Block or intercept specific key actions
• Create global hotkeys and keyboard shortcuts
• Record and replay keyboard events

Writing Text and Key Combinations

Use keyboard.write() to simulate typing and keyboard.press_and_release() for key combinations ?

import keyboard
import time

# Write text automatically
keyboard.write("Hello TutorialsPoint!")

# Simulate key combinations
keyboard.press_and_release('ctrl+a')  # Select all
keyboard.press_and_release('ctrl+c')  # Copy

# Press individual keys
keyboard.press_and_release('enter')
keyboard.press_and_release('tab')

Waiting for Key Events

The keyboard.wait() method blocks execution until a specific key is pressed ?

import keyboard

print("Type some text, then press 'esc' to exit...")
keyboard.wait('esc')
print("Program terminated!")

# Wait for key combinations
print("Press Ctrl+Q to quit...")
keyboard.wait('ctrl+q')

Creating Hotkeys

Register callback functions that execute when specific key combinations are pressed ?

import keyboard

def on_hotkey():
    print("Hotkey activated!")

def save_file():
    print("File saved!")

# Register hotkeys
keyboard.add_hotkey('ctrl+shift+h', on_hotkey)
keyboard.add_hotkey('ctrl+s', save_file)

print("Hotkeys registered. Press Ctrl+Shift+H or Ctrl+S")
keyboard.wait('esc')  # Keep program running until ESC

Recording and Replaying Events

Record keyboard activity and replay it later ?

import keyboard

print("Recording started. Press 'esc' to stop...")
recorded = keyboard.record(until='esc')

print("Recording stopped. Press 'space' to replay...")
keyboard.wait('space')

print("Replaying recorded events...")
keyboard.play(recorded, speed_factor=1)

Common Methods

Important Considerations

• Permissions: Requires administrator privileges on most systems
• Security: Use responsibly as it can simulate user input
• Platform differences: Key names may vary between operating systems
• Testing: Test thoroughly before deploying keyboard automation scripts

Conclusion

The keyboard module provides powerful functionality for automating keyboard input and creating interactive applications. Use it responsibly with proper permissions for tasks like automation scripts, accessibility tools, and custom keyboard shortcuts.
