Flask is a small, lightweight, and micro web framework written in Python. It allows you to develop web applications easily without any tools or libraries. This web application may be a blog, wiki page, web pages, web-based calendar application, or a commercial website. It is simple, easy to use, easy to learn, and beginner-friendly because it does not require any dependencies.
