In this article, I’d like to share with you the articles I found most interesting and insightful (inspiring) last year and this year (so far). My other goal was to create a comprehensive list of the most valuable pieces for my Python students.

Python 3.7 is set to be released this summer, let’s have a sneak peek at some of the new features! If you’d like to play along at home with PyCharm, make sure you get PyCharm 2018.1 (or later if you’re reading this from the future). There are many new things in Python 3.7: various character set improvements, postponed evaluation of annotations, and more. One of the most exciting new features is support for the dataclass decorator.

PySide2 – the bindings from Python to Qt – changes skin this spring. We have re-branded it as Qt for Python on a solution level, as we wanted the name to reflect the use of Qt in Python applications. Under the hood it is still PySide2 – just better.

tl;dr Python comprehensions can have duplicate function calls (e.g. [foo(x) for x in ... if foo(x)]). If these function calls are expensive, we need to rewrite our comprehensions to avoid the cost of calling them multiple times. In this post, we solve this by writing a decorator that converts a function in to AST, optimizes away duplicate function calls and compiles it at runtime in ~200 lines of code.

If you look at the new Datadog Agent, you might notice most of the codebase is written in Go, although the checks we use to gather metrics are still written in Python. This is possible because the Datadog Agent, a regular Go binary, embeds a CPython interpreter that can be called whenever it needs to execute Python code. This process can be made transparent using an abstraction layer so that you can still write idiomatic Go code even when there’s Python running under the hood.

In this tutorial, we provide step-by-step instructions to go from loading a pre-trained Convolutional Neural Network model to creating a containerized web application that is hosted on Kubernetes cluster with GPUs on Azure Container Service (AKS). AKS makes it quick and easy to deploy and manage containerized applications without much expertise in managing Kubernetes environment. It eliminates complexity and operational overhead of maintaining the cluster by provisioning, upgrading, and scaling resources on demand, without taking the applications offline. AKS reduces the cost and complexity of using a Kubernetes cluster by managing the master nodes for which the user does no incur a cost.

I don’t particularly enjoy writing tests, but having a proper testing suite is one of the fundamental building blocks that differentiate hacking from software engineering. Sort of like sending your application to the gym, if you do it right, it might not be a pleasant experience, but you’ll reap the benefits continuously. At work we are especially big fans of the testing pyramid, and having dozens of unit tests give us the support that we need to deliver high quality software with rapid delivery to production.
