Who uses
was originally published while Aaron Swartz worked at, where the site used it as it grew to become one of the top 1000 sites according to Alexa and served millions of daily page views. “It’s the anti-framework framework. doesn’t get in your way, ” explained founder Steve Huffman. (The site was rewritten using other tools after being acquired by Condé Nast. )
Some user testimonials:
“In the ecosystem of web frameworks, something must occupy the niche of ‘small, light, and fast’: does this. ”*
— Lloyd Dalton,
“[ inspired the] web framework we use at FriendFeed [and] the webapp framework that ships with App Engine…”*
— Brett Taylor, co-founder of FriendFeed and original tech lead on Google App Engine
“Django lets you write web apps in Django. TurboGears lets you write web apps in TurboGears. lets you write web apps in Python. ”*
— Alice Atlas
“Guido* [van Rossum, creator of Python], you’ll probably find that best suits your style. … If you don’t like it, I can’t imagine which of the other dozens of frameworks out there you would like. ”

Web Development – Full Stack Python
Web development is the umbrella term for conceptualizing, creating,
deploying and operating web applications and
application programming interfaces
for the Web.
Why is web development important?
The Web has grown a mindboggling amount in the number of sites, users and
implementation capabilities since the
first website went live
in 1989. Web development is the concept
that encompasses all the activities involved with websites and web
applications.
How does Python fit into web development?
Python can be used to build server-side web applications. While a
web framework is not required to build web apps,
it’s rare that developers would not use existing open source libraries to
speed up their progress in getting their application working.
Python is not used in a web browser. The language executed in browsers
such as Chrome, Firefox and Internet Explorer is
JavaScript. Projects such as pyjs
can compile from Python to JavaScript. However, most Python developers
write their web applications using a combination of Python and JavaScript.
Python is executed on the server side while JavaScript is downloaded to
the client and run by the web browser.
Web development resources
To become an experienced web developer you need to know the foundation
principles that the web is built with, such as HTTP requests and responses,
client (typically web browsers) and server (web servers
such as Nginx and Apache
architectures, HTML,
CSS and JavaScript, among
many other topics. The following resources provide a range of perspectives
and when combined together should get you oriented in the web development
world.
How the Internet works
is a must-read to get a quick overview of all the pieces that go into
a network connection from one machine to another. The example explains how
an email is sent and the story is just as useful for learning about other
connections such as downloading a webpage.
If you want to be a web developer it’s important to know the foundational
tools used to build websites and web applications. It is also important to
understand that the core concepts such as
HTTP, URLs and HTML were all there
at the beginning and then were expanded with new specifications over time.
This article on the
History of the Web
succinctly explains the origins of the web starting from Tim Berners-Lee’s
origin vision and release at CERN.
Web Architecture 101
is a great high-level overview of the technologies that run the modern
web, such as DNS, load balancers, web application servers (for Python
that equates to WSGI servers),
data bases, task queues,
caching and several other critical concepts.
What happens when? is an
incredibly detailed answer to the questions “What happens when you
type into your browser’s address box and press enter? ” that
seems straightforward on the surface until you really dig in.
How browsers work
provides an overview with solid detail on how browsers take the HTML,
CSS, JavaScript, images and other files as input and render webpages as
output. It is well worth your time to know this stuff as a web developer.
The history of the URL
explains how the growth of ARPANET to hundreds of nodes eventually led to
the creation of the URL. This is a great read that provides historical
context for why things are the way they are with the web.
The Browser Hacker’s Guide to Instantly Loading Everything
is a spectacular technical talk given by Addy Osmani at JSConf EU 2017
that has great bits of developer knowledge for both beginner and
experienced web developers alike.
Build a web application from scratch
and its follow on posts for
request handling
middleware explores
the fundamentals of web development. Learning these foundational concepts
is critical for a web developer even though you should still plan to use an
established web framework such as
Django or Flask to build real-world
applications. The
open source code
for these posts is available on GitHub.
While not Python-specific, Mozilla put together a
Learning the Web tutorial
for beginners and intermediate web users who want to build websites.
It’s worth a look for general web development learning.
Web development involves HTTP communication between the server, hosting
a website or web application, and the client, a web browser. Knowing
how web browsers works is important as a developer, so take a look at
this article on
what’s in a web browser.
Ping at the speed of light
dives into the computer networking weeds with how fast packets travel through
the internet plumbing. The author created a
Python script that scrapes network speeds
from disparate locations to see what the network speed is in fiber optic
cables as a percentage of the speed of light.
The critical path: optimizing load times with the Chrome DevTools
provides a well-written explanation about using Chrome’s developer
features to improve the performance of your websites and web applications.
Three takeaways for web developers after two weeks of painfully slow Internet
is a must-read for every web developer. Not everyone has fast Internet
service, whether because they are in a remote part of the world or they’re
just in a subway tunnel. Optimizing sites so they work in those situations
is important for keeping your users happy.
The History of the URL: Path, Fragment, Query, and Auth
gives a comprenhensive historical perspective on the fundamental
way to link to resources on the web. This post should be required reading
for web developers.
Quantum Up Close: What is a browser engine?
explains how a browser takes in
HTML,
JavaScript,
CSS,
images and any
other data and files to produce a webpage as output.
How to understand performance tests
is an important topic because many websites are slow and bloated.
Learning about improving the performance of your site is one of
the best ways to become a better web developer. Another great article on
website performance is
The average web page is 3MB. How much should we care?.
The visuals alone tell a compelling story about how large webpage
sizes have grown in recent years.
Let’s get started. What do you want to learn right now?
