What are the benefits of using wtforms vs html for forms when using flask?
WTForm is a lightweight and fast form library for Flask, built on top of Werkzeug (the Python WSGI server). It offers a comprehensive set of features to create clean and maintainable web forms, including:

Field validation: WTForm provides built-in support for validating user input via various checks such as required fields, length constraints, email validation, etc.

Simple syntax: The API of WTForm is simple and intuitive, making it easy for developers to get started with basic form creation.

Integrated templates: WTForm includes built-in Templates that allow you to easily generate HTML form fields based on data from your model.

Separation of concerns: WTForm separates the business logic of handling form submission from the rendering of forms themselves, which can make your application more scalable and maintainable in the long run.

Flexible form layout: WTForm allows you to create customizable forms with different fields arranged into columns or rows, depending on your needs.

WTF Form does not require any external libraries, unlike some other popular Flask form libraries like Bootstrap or Select2. This means that there are no runtime dependencies to worry about, and your app will work out of the box with minimal setup time. Additionally, since WTForm uses Werkzeug under the hood, it has full compatibility with Flask's existing debugging tools and extensibility APIs. So, if you're looking to build a high-quality, reliable website using Flask, WTForm is definitely worth considering!
