We will be retiring the beta shortly and will be removing the button to get to it and ceasing support for it. The beta garnered negative feedback from the Stack Overflow community, including observations that it looked more like a general discussion site such as Reddit and was losing the essence of what made it successful: precise questions and community-validated answers.

Akismet launched in 2005 as a web service to classify user-generated content as spam or not, quickly gaining popularity among bloggers facing spam issues.

New overloads on TarFile.CreateFromDirectory accept a TarEntryFormat parameter, giving direct control over the archive format. Previously, CreateFromDirectory produced Pax archives. The new overloads support all four tar formats—Pax, Ustar, GNU, and V7—for compatibility with specific tools and environments.

With PyCharm 2026.1, users can leverage a comprehensive set of editing and formatting tools for modern web languages, including basic React support with code completion and navigation.

The toString() method is very simple. You can call it on anything, and if nothing has been defined, it'll use the default version. Many objects, like arrays, do define their own version. Custom objects can also define a version. When you interpolate an object into a string literal- console.log("This is my object: " + myObject)-it will call the toString() method.

Readable failures. When something breaks, I want to understand why in seconds, not minutes. Predictable setup. I want to know exactly what state my tests are running against. Minimal magic. The less indirection between my test code and what's actually happening, the better. Easy onboarding. New team members should be able to write tests on day one without learning a new paradigm.

LBYL came more naturally to me in my early years of programming. It seemed to have fewer obstacles in those early stages, fewer tricky concepts. And in my 10+ years of teaching Python, I also preferred teaching LBYL to beginners and delaying EAFP until later. But over the years, as I came to understand Python's psyche better, I gradually shifted my programming style-and then, my teaching style, too.

Mocking in Python with unittest.mock allows you to simulate complex logic or unpredictable dependencies, such as responses from external services. The Mock class can imitate real objects, and the patch() function lets you temporarily substitute mocks for real objects in your tests.
