Course Highlights

① Introduction:

Flask uses Werkzeug for handling HTTP requests and responses, and Jinja2 for rendering HTML templates.
PEP 3333 is a proposal that led to the WSGI (Web Server Gateway Interface) standard, implemented by Werkzeug.

② API (Application Programming Interface):

Examples of JSON and XML formats used in a weather system API interaction.

JSON Example:

{
    "location": "New York",
    "temperature": "15°C",
    "condition": "Partly Cloudy"
            }

XML Example:


    New York
    15°C
    Partly Cloudy

e.g.: A weather system API interaction, the API acts as a middleman between the weather data provider and the client application.
The application sends requests to the API, and the API responds the state with weather data formatted in either JSON or XML,
which the application then parses and displays to the user.

④HTTP Methods:

Introduction to various HTTP methods like GET, POST, PUT, DELETE, PATCH, OPTIONS, and HEAD for CRUD (Create, Read, Update, Delete) operations.

⑤HTTP Status Codes:

⑤ How It Works:

Explanation of a Flask application running a feedback form, with JavaScript and Python Flask backend interaction.

When you run this Flask application and navigate to http://127.0.0.1:5000/feedback, You'll see a simple feedback form.
When the user submits feedback, a JavaScript function handles user interactions and back-end Python code (in this case, using Flask) for processing and storing the data.
The script.js file now collects and displays the selected options in an alert box.

⑥ Challenging Aspects:

For a more robust solution, you might want to consider using a database.(e.g.: SQLite)

⑦ Ideas to Enhance the Application:
