Flask is a Python web framework that offers tools, libraries, and technologies to developers to build web applications. It is considered a micro-framework that focuses on keeping its code extensible and straightforward.

Flask’s independency on external libraries to perform framework tasks makes it simple, flexible, and independent, which is why a lot of developers prefer to begin with Flask.

However, Flask does have two dependencies. They are Werkzeug, a Web Server Gateway Interface (WSGI) utility library, and Jinja2, a template engine.
Werkzeug is a utility library and a toolkit of WSGI used in Python programming. It can register the software for functions related to request, response, and utility. It can also be used to build a framework that supports Python 2.6, 2.7, and 3.3.

Jinja2 is a template engine for programming using Python web framework to build a basic layout of the page.

Benefits:

• It is scalable: Flask is simple to use and has few dependencies that enable it to run smoothly even after scaling.
• It is Flexible: Flask has a minimal nature and is helpful in developing smaller web applications that offer flexibility.
• It is easy to understand: The Flask microframework is easy to understand and offers developers more control over their code.
• It offers a lightweight design: It offers the developers control over constitutable parts of the code as they are moveable and customizable.

Features:

• Flask is independent of external libraries which makes it a lightweight framework. It offers a quick start to web development that have complex applications.
• It is compatible with the latest technologies like Machine Learning, Cloud Computing, Agile Development, etc.
• Flask provides developers with complete control over creating web applications. Developers can experiment with different libraries and architecture in the framework.
• It offers developers an integrated unit testing feature that supports faster debugging, robust development, and the independence to experiment.
• Flask supports WSGI templates that help enhance its scalability and flexibility in web development.
• It supports secure cookies – an attribute of an HTTP request that enables channel security to ensure that only authorized persons can access the text. Basically, Flask supports the secure cookies feature.
