Sanest, sane nested dictionaries and lists for Python

Sanest, sane nested dictionaries and lists for Python launched on July 2, 2017 with 5 votes, #1,486 of 2,972 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 9 years on.

What it does

The code is now type-safe and will fail fast on unexpected input data. sanest is a Python library that makes it easy to consume, produce, or modify nested JSON structures in a strict and type-safe way.

It aims for the sweet spot between ‘let’s hope everything goes well’ (if not, unexpected crashes or undetected buggy behaviour ensues) and rigorous schema validation…from sanest.readthedocs.io

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
