Book Management API with FastAPI

This project is a simple FastAPI application to manage a collection of books using in-memory storage. It demonstrates CRUD operations and data validation.

Features

1. Book Model:

   • id (UUID): Unique identifier for each book.
   • title (string): Book title (min length: 1 character).
   • author (string): Author name (2–60 characters).
   • desc (string): Book description (5–100 characters).
   • rating (integer): Book rating (0–100).

2. API Endpoints:

   • GET /: Fetches the list of all books.
   • POST /: Adds a new book to the collection.
   • PUT /{book_id}: Updates details of a book by its UUID.
   • DELETE /{id}: Deletes a book by its UUID.

3. Validation:

   • Input data is validated using pydantic's Field() constraints.
   • Ensures required formats and lengths for fields like title, author, desc, and rating.

4. Error Handling:

   • If a book's UUID is not found during updates or deletions, a 404 Not Found error is raised using HTTPException.

This API is designed for learning purposes and currently uses in-memory storage for simplicity.
