The Quest for Faster Python
There seems to be a lot going on in the Python JIT compiler space. Facebook recently open-sourced Instagram’s Cinder runtime, Pyston 2 returned as an open-source project, and the Pyjion project from Microsoft continues to grow. But Python creator Guido van Rossum has suggested that Python developers in need of more performance should consider writing parts of their code as C extensions, or use the PyPy runtime. This article explores Pythons turbulent history with performance optimization.

Async in Flask 2.0
This article looks at Flask 2.0’s new async functionality and how to leverage it in your Flask projects. You’ll learn how Flask processes requests asynchronously using a traditional WSGI server, instead of the ASGI server used by many other async web frameworks. You’ll also learn how to simulate Flask 2.0 async in Flask 1.X applications.

What Is WSGI and Why Do You Need Gunicorn and nginx in Django?
Django is one of the most popular Python web frameworks. But you can’t run a web application with Django alone. You need a host of other tools in place to deploy a Django project, from a server to run your application to a server to handle incoming requests. In this article, you’ll learn about Gunicorn and Nginx and how they work together with Django to deliver a web application to your users.

PEP 654: Exception Groups and except*
Currently, Python’s exception handling mechanisms only allow you to focus on a single exception at a time. PEP 654, which is still in draft, aims to change that by adding to the Python language the concept of an exception group. Learn about this proposed feature in this article covering the discussion about exception groups from the 2021 Python Language Summit

Create Web Applications Using Only Python With Anvil
What if you could create an application and deploy it to the web with just Python? Wouldn’t it be nice to skip the additional full-stack development steps of learning three different languages in addition to Python? That’s the idea behind Anvil. This week on the Real Python Podcast, we have Meredydd Luff, co-founder of Anvil.

How to Troubleshoot Memory Problems in Python
Memory problems can be frustrating. They’re hard to diagnose and fix, and memory issues in Python applications can be especially frustrating thanks to the language’s garbage collection system. In this article, you’ll learn a six-step process for troubleshooting memory problems that the EvalML team used to solve a tricky problem with their library.

Why is a, b = b, a not always equivalent to b, a = a, b?
In Python you can swap the values of two variables without creating a temporary variable. So, if you have two variables a = 1 and b = 2, you can swap their values using a, b = b, a. Now a has the value 2 and b has the value 1. So shouldn’t b, a = a, b do the same thing? In most cases, it will, but one user on Stack Overflow found an instance where they don’t, and the explanation gets into the nitty-gritty about how assignments are evaluated.
