App Service is Microsoft Azure's platform-as-a-service offering for web apps, whether they are sites accessed through a browser, REST APIs used by your own clients, or event-triggered processing.

Idiomatic Python: EAFP versus LBYL

Brett Cannon

One idiomatic practice in Python that often surprises people coming from programming languages where exceptions are considered, well, exceptional, is EAFP: "it's easier to ask for forgiveness than permission". Quickly, EAFP means that you should just do what you expect to work and if an exception might be thrown from the operation then catch ...

How to debug Python Azure Worker Roles

May 10, 2016 May 10, 2016 05/10/16

Christopher Wilcox

Two months ago I wrote a blog post on Python 3 Adoption. If you want to read the first post you can find it here. In the two months since that blog post was written we have more data to process and I got to thinking: why shouldn't we scale this up and increase the performance a bit? You'll recall that I used a worker role on Azure to process ...

Idiomatic Python: boolean expressions

April 18, 2016 Apr 18, 2016 04/18/16

And while the general concept is simple, there are some idiomatic practices...

Steve Dower

Python's packaging ecosystem is one of its biggest strengths, but Windows users are often frustrated by packages that do not install properly. One of the most common errors you'll see is this one: (image) As far as errors go, "unable to find vcvarsall.bat" is not the most helpful. What is this mythical batch file? Why do I need it?

Brett Cannon

When working in the open source world it is very important that everyone feels welcome and safe. External contributors to a project need to feel welcome so that they want to contribute to the project. Since contributing to open source is an inherently social event due to the fact that there will be interactions through issues, code reviews, ...
