CRUD Assignment

 CRUD Assignment

1. Create a new API Endpoint that can fetch all books from a specific author using either Path Parameters or Query Parameters.

Code and Result:

As async is implemented by FastAPI itself hence ignored it.
from fastapi import FastAPI

app = FastAPI()

BOOKS = [
        {"title": "Book One", "author": "Author A", "category": "Fiction"},
        {"title": "Book Two", "author": "Author B", "category": "Non-Fiction"},
        {"title": "Book Three", "author": "Author A", "category": "Biography"},
        {"title": "Book Four", "author": "Author A", "category": "Historical"},
        {"title": "Book Five", "author": "Author A", "category": "Romance"},
        {"title": "Book Six", "author": "Author A", "category": "Science Fiction"}
    ]

@app.get("/books/{book_author}") # Dynamic path parameter is used here.
def read_all_books_by_author(book_author: str):
    """
    This function returns the list of books based on the author.
    """
    book_to_return = []
    for book in BOOKS:
        if book.get('author').casefold() == book_author.casefold():
            book_to_return.append(book)
    return book_to_return

@app.get("/books/") # query parameter is used here.
def read_books_by_author(author: str = None):
    """
    This function returns the list of books based on the category.
    """
    book_to_return = []
    for book in BOOKS:
        if book.get('author').casefold() == author.casefold():
            book_to_return.append(book)
    return book_to_return

Python Variables

Python Variables   Variables: They are containers for holding data values. It will help you store the value in a memory location. example: cost = 10 print(cost) Now cost variable will direct you to get the information stored over the memory location which is holding the data 10. Variables help you to create formulas or help to reuse the data over different locations in a code. example: cost=10 tax_percent = 0.25 tax = cost * tax_percent price = cost I+ tax print(price) String datatype variable sample: username="Rock!rupesh" first_name="Rahul" print(username) print(first_name) print(username + " " + first_name) first_number=10 second_number=2 print(first_number) print(second_number) first_number=1 So you can modify the variable stored information according to your need. So as a summary variables are memory location which hold relevant information for your application.
