This blog post is based on From Project to Productionized, a talk given at PyCon 2020 at the height of the COVID-19 pandemic. You can use this post today to learn how to deploy a Python application on Heroku. More specifically, we’ll show you how to deploy Django apps, including setting up your Django configuration, building continuous delivery pipelines, adding middleware, and everything else that goes into deploying Django on Heroku. If you’d prefer a generic guide explaining how to deploy a Python application on Heroku, check out Getting Started on Heroku with Python. https://www.youtube.com/embed/1923eduj0Gg Imagine that you’ve just spent the last…

If you're like me, or like many other Python developers, you've probably lived (and maybe migrated) through a few version releases. Python 3.7(.3), one of the latest releases, includes some impressive new language features that help to keep Python one of the easiest, and most powerful languages out there. If you're already using a Python 3.x version, you should consider upgrading to Python 3.7. Read on to learn more about some of the exciting features and improvements. Data Classes One of the most tedious parts about working with Python prior to 3.7 in an object-oriented way was creating classes to…

Andrey Petrov is the author of urllib3, the creator of Briefmetrics and ssh-chat, and a former Googler and YCombinator alum. He’s here to tell us of a dangerous expedition his requests undertook, which sent them from Python, through the land of C, to a place called Go (and back again). Today we're going to make a Python library that is actually the Go webserver, for which we can write handlers in Python. It makes Python servers really fast, and—more importantly—it’s a bit fun and experimental. This post is a more detailed overview of my PyCon 2016 talk of the same…

Today, we're thrilled to host Jacob Kaplan-Moss. Jacob's a former Herokai and long-time core contributor to Django, and he's here to share an in-depth look at something that he believes will define the future of the framework. Django Channels allows Python developers to build real-time, asynchronous web apps with Python and JavaScript. It augments Django’s robust response-request architecture with asynchronous protocol handling, including WebSockets support. In this Django Channels tutorial, we’ll show you how to build a real-time chat app with Django, Channels, Redis, and Heroku Dynos. What are Django Channels? When Django was created, almost 20 years ago, the…

A big update to the beloved Python web framework known as Django was released recently: Django 1.9. This release contains a long list of improvements for everything from the graphical styling of the admin to the ability to run your test suite in parallel. Our favorite improvements to the framework were, of course, all about our favorite database: Postgres. Here are some of the highlights from the official release notes (highly recommended reading). Renamed PostgreSQL Back-end Django's fantastic built-in Postgres database back-end received a nice name change. Previously known as django.db.backends.postgresql_psycopg2, the back-end will now be officially available as the…

Celery is by far the most popular library in Python for distributing asynchronous work using a task queue. If you're building a Python web app, chances are you already use it to send email, perform API integrations, etc. Many people choose Redis as their message broker of choice because it's dead simple to set up: provision a Redis add-on, use its environment variable as your BROKER_URL, and you're done. But the simplicity of Redis comes at a cost. Redis does not currently support SSL, and it doesn't seem like that's going to change any time soon. Because Heroku add-ons communicate…

When we think of the concept of Waza (技) or "art and technique," it's easy to get caught up in the idea of individual mastery. It's true that works of art are often created by those with great skill, but acquiring that skill is neither solitary nor static. Generations of masters contribute to a canon and it is in that spirit that we built the Heroku platform and the Waza event. This year's Waza was no exception. On February 28th, more than 900 attendees participated in Waza including Ruby founder Yukihiro "Matz" Matsumoto, Django co-creator Jacob Kaplan-Moss and Codeacademy’s Linda…
