Pillars of Python: Pyramid Web framework.



Pyramid is a Python Web framework being developed as part of the Pylons Project. Pyramid 1.0 was released this year. Prior to that, the Pylon Project's Web framework was, not surprisingly, Pylons. But Pylons has now entered legacy mode; the project website promises that Pylons will "continue to be maintained, but not enhanced." 


Pyramid will run on any 2.x Python that is later than version 2.4. In addition, Pyramid can be run on the Java-based Python variant, Jython. The framework is based on the repoze.bfg framework -- sometimes simply called BFG -- with some additions. Pyramid incorporates concepts inspired by Zope, Pylons, and Django. It's important to note that Pyramid is not an update of Pylons; the two frameworks share no common code. Pylons programmers need not be left out in the cold, however. The Pylons Project provides a fallback wrapper that allows Python web application development to run inside Pyramid, thus permitting Pylons developers to incrementally port their applications to Pyramid.


Pyramid is "policy free," meaning that Pyramid makes no assertions about the database you should use or place any strict requirements on the templating system employed. In fact, documentation says that Pyramid's template system is included only for convenience. Nor does Pyramid fit neatly into the MVC paradigm -- as with Django, there's no clear controller component. However, Pyramid goes a step further with its policy-free attitude: It's hard to find a model component.


The initial rush to build mobile apps is settling down, and none too soon. The world has endured the release of a whole lot of mediocre, or even useless, mobile apps. App stores everywhere are chock-full of them. Many companies were gripped by a burning need to create mobile apps for little more than bragging rights. What such apps did for users was often an afterthought. As a result, many corporate apps have languished in app libraries with very few downloads.
Some organizations will probably let it rest there, but others may learn from their mistakes and set out to create better apps. Here are some best practices that your company can employ to ensure that any apps you develop in the future are more intriguing to users:
