File Handling
Reading and Writing Files
Learning Goals
The Core Concept
File handling allows your Python script to read data from local files and write results back to files. Python provides built-in functions to open, read, write, and append to files.

Hands-on practice task
The Challenge
Write a script that scans a specific directory and organizes files into sub-folders based on their file extensions (e.g., .txt into a 'Text' folder, .jpg into an 'Images' folder).
Helpful Hints
- •Use the 'os' and 'shutil' modules.
- •Use os.listdir() to get all files in a folder.
- •Extract the file extension and use os.makedirs() to create the target folder if it doesn't exist.
- •Use shutil.move() to relocate the files.
