Flask and Django are two of the most popularly used web frameworks for Python.
Provides a full-featured Model-View-Controller Framework. Django has the goal of simplifying the process to create a website which is, usually, complex and database-driven. It provides the reusability of the code and rapid development.
Is a micro-framework that believes in the concept of doing one thing, and doing it well. It does not need any tools or libraries. It also does not possess any database abstraction layer(i.e. a third party based built-in libraries and common functions).
However, it does provide several ways of extensions which are definitely used as if they are the built-in flask itself. Extensions are needed as part of mappers, form validations, upload handling, and many other framework tools.
|Structure||It is a free open source framework and uses MVC pattern.||It is a framework without external libraries and tools.|
|Features||Unit-testing, Serialization, dispatcher, inheritance, caching||Unicode based, jinja2 templates, unit testing, high flexibility.|
|Sites using these frameworks||Nextdoor, Mozilla, Instagram, Times||Pinterest, Linkedin|
|Project layout||Conventional structure||Arbitrary structure|
|Flexibility||Inclusion of setting flexibility.||Permutations for Flask code = no. applications in flask already.|
|Routing mechanism||Urls .py used to connect properties.||Latter is sorted in default order before patterns matched with Urls.|
Both Django and Flask are excellent in their own market and domains. However, Django provides the advantage of being a full stack framework, whereas Flask is a micro/smaller framework.
Generally, users prefer Django over flask due to its variety, but your choice of framework really depends on your project’s requirements.
