In this FastAPI tutorial, we learn how to *update existing data* using *PUT* and *PATCH* requests.

These are two important HTTP methods used in REST APIs, and many beginners get confused about the difference between them. In this video, we clearly explain:

*PUT* → Replace the entire resource
*PATCH* → Update only selected fields

Using a simple Books API example, we build both endpoints step by step and understand when to use each one.

What you'll learn:

What PUT request does
What PATCH request does
PUT vs PATCH difference
Full update vs partial update
How to create PUT endpoints in FastAPI
How to create PATCH endpoints in FastAPI
Optional fields with Pydantic
Using `exclude_unset=True`
Returning updated data
Handling "Book not found" errors

Endpoints covered:

`PUT /books/{book_id}`
`PATCH /books/{book_id}`

Example requests:

Replace an entire book using PUT
Update only the title or author using PATCH

By the end of this video, you'll clearly understand how updating data works in FastAPI and when to choose PUT or PATCH in real-world APIs.

FastAPI makes API development simple and clean—and understanding these update methods is an essential step toward building complete CRUD applications.
