Compare Django and web2py

Django is Python web framework that encourages rapid development. It is based model-template-view (MTV) design pattern. It follows a "batteries included" philosophy and ships with many tools that are needed by application developers such as ORM framework, admin panel, directory structure and more.

web2py was originally designed as a teaching tool, but it gained adoption outside of the academic world. It is a full-stack framework containing all the components needed to build fully functional web applications using the Model View Controller (MVC) pattern. Inspired by the Ruby on Rails and Django. It is not very popular right now but was ranked amongst top Python web frameworks in 2011.

Let's see how Django and web2py compare on various factors and features and which to choose when.

Performance [?]

Performance [?]
4.5 Stars
Not as fast as compared to bare-bones Flask or other microframeworks, but for many real-world use cases, the difference is negligible.
Performance [?]
3 Stars
Web2py takes a unique approach where models and controllers are executed in a single global environment, which is initialized at each HTTP request. While there are pros to this approach, such as developers never having to worry about cleaning up or avoid conflict between requests, the major disadvantage is that the code is models is executed with every request which carries a performance penalty.

Flexibility

Flexibility
4.5 Stars
Django expects things to be done in a certain way unlike microframeworks (e.g. Flask) which have no opinion on how developers structure things. However, It does this without compromising on flexibility. Django has been used to build a variety of things from content management systems to social networks to scientific computing platforms.
Flexibility
3 Stars
Not as flexible as microframeworks, but doesn't always get in the way.

Ease of Learning

Ease of Learning
5 Stars
Has a learning curve especially for those who are not familiar with other web frameworks. But there are some great online resources, courses tutorials and YouTube videos.
Ease of Learning
2 Stars
Limited online tutorials and resources, and many are several years old. The best resource for learning is web2py author's own "web2py Complete Reference Manual", which seems to be written in 2013.
