Flask

Flask is a lightweight, open-source web framework for Python. It is designed to be simple and easy to use, allowing developers to build web applications quickly and with minimal code. Flask follows a **microframework** approach, meaning it provides only the basic tools to get a web app up and running, while giving developers the freedom to add additional components as needed.

-Key Features of Flask:
1. Lightweight and Simple:
  - Flask is minimalistic and provides just the essentials for building a web application. This simplicity allows for flexibility and makes it easy to learn, especially for beginners.

2. Routing:
  - Flask has a built-in routing system that helps map URLs to Python functions. This makes it easy to define endpoints and handle HTTP requests like GET, POST, etc.

3. Templating with Jinja2:
  - Flask uses **Jinja2** as its templating engine, allowing developers to generate dynamic HTML pages by embedding Python code into HTML templates.

4. Development Server:
  - Flask comes with a built-in development server, so developers can easily test their applications locally without needing additional tools.

5. Extensibility:
  - Flask provides extensions that add functionality like database integration, form handling, authentication, and more. These extensions can be easily added when needed.

6. RESTful API Support:
  - Flask is often used to build **RESTful APIs** because of its simplicity and flexibility, making it easy to build APIs that communicate with other services.

Why Use Flask?
- Flexibility: Flask gives developers complete control over how they structure their applications and which components to use, making it ideal for small projects or when you need full control.
- Simplicity: Flask is easy to set up and use, which makes it perfect for beginners or small projects.
- Extensibility: You can add new features to Flask apps using various extensions, from database support to user authentication.
- Fast Development: Flask allows you to quickly develop web applications without the overhead of a larger framework.
