Keylogger Notes:

🧠 Key Concepts Used

• pynput library: for controlling and listening to mouse and keyboard.
• File handling: Reading, writing, appending to text files.
• Event listeners: React to keyboard or mouse inputs.
• OOP: Controller objects for mouse and keyboard automation.

📦 1. Library Imports

from pynput.mouse import Listener as MouseListener, Controller as MouseController
from pynput.keyboard import Key, Listener as KeyboardListener, Controller as KeyboardController

✍️ Explanation:

• Listener: used to listen for input events.
• Controller: used to simulate (control) input devices.
• as: gives custom names for easier reference (avoid confusion when using both mouse and keyboard listeners).

📂 2. File Handling in Python

Examples in the comments demonstrate basic file operations:

🔁 Using with:

with open("log.txt", "a") as f:
    f.write("Hello World\\n")

• Auto-closes the file (memory-efficient and cleaner syntax).
