The document introduces Pyramid, an open-source web framework designed for building a variety of web applications with a focus on performance and flexibility. It discusses the framework's advantages, including its simplicity, minimalism, and extensive documentation, as well as the community support available for developers. Additionally, it outlines the basic steps for getting started with Pyramid and highlights its features like routing methods and templating engines.

Demo & Questions

3. What is Pyramid
● An open source web framework
● Easier to create arbitrary web apps
● Can be used to build wide array of
applications
● Simple Blogs, CMS, Social Web Apps
...etc

4. What makes Pyramid Awesome
● Pyramid is a fast and flexible web framework
● Beats similar web frameworks in many
performance metrics
● Component Architecture
● More choices and flexibility
● Learn from and contribute back to the Pylons
Community

5. Brief History
Well, sadly enough I hate history
Pylons + Repoze.bfg

6. Brief History
● Pylons,TurboGears, Django(2005-)
● Repoze.bfg (2008-2010)
● Influenced by Zope* (1998?-)
● Pylons, Repoze.bfg, TG merge into The Pylons
Project (2010)
● A collection of web related Python projects under
a single umbrella
● Pylons development discontinued
● Repoze.bfg renamed to Pyramid
● Pyramid currently the main web framework

7. Getting started
● $ virtualenv env
● $ cd env
● $ source bin/activate
● $ easy-install pyramid [nose]
● $ pcreate -s starter HelloWorld

8. Your first Web Application

9. The Pyramid Tenets
● Simplicity
● Minimalism
● Documentation
● Reliability
● Openness
● Speed
*https://www.pylonsproject.org/projects/pyramid/about

10. Simplicity
"Only pay for what you eat"
● Not forced to user any particular technology
● No DB
● SQL
● MongoDB
All okay
Easy to set up basic apps

11. Minimalism
Relatively small code base (~5000 lines)
Django ~60,000 lines
Concentrates on common core activities:
● URL mapping,
● templating,
● security,
● serving static assets

12. Documentation
Every aspect of the framework is documented
● Coverage is good, but sometimes lacks good
examples
● Improving over time
● You can learn by examples too on github, clone
and just hack away.
https://docs.pylonsproject.org/

13. Reliability
● Tested exhaustively
● 100% code test coverage
● “If it ain’t tested, it’s broke"
● Source code has good examples of well written tests
Unit testing is very important.

14. Openness
"As with Python, the Pyramid software is distributed
under a permissive open source license."
● Active community
● Main developers Chris McDonough, Ben Bangert, and
others respond to question frequently
● Growing library of open source pyramid related
projects

15. Speed
Core functionality is optimized for very fast execution
● Hardware maybe cheap these day
● The time and energy needed to manage all that
hardware is not so cheap

16. Two methods of routing requests
URL Dispatch
● Simple pattern matching
● Maps a view function to a URL pattern
Traversal
● Analogous to opening a file/directory in your OS's file
system
● Stick with URL Dispatch if you're a beginner
Templating Engine
● Chameleon and Mako support
● I prefer Mako's syntax

17. Community
Community Contributions
● Pyramid projects on Github
● Best way to learn (other than documentation)
Many pyramid_* packages and continuing to grow
