Hey there, Python friends! Welcome back to another episode of the Python podcast. I'm your host, and wow, do we have some exciting updates from the CPython repository to dive into today. Grab your favorite beverage because we're talking about some really cool performance improvements and quality-of-life enhancements…
Let's jump right into the big story of the day - and it's all about speed! Our contributor kangtastic just merged what I think is one of the most impactful performance improvements we've seen in a while. They added native base32 support directly to the binascii module, implemented in C. Now, if you've ever worked…
This change is absolutely beautiful in its execution. Instead of rewriting everything from scratch, they've made the existing base64 module functions into lightweight wrappers around these new, blazingly fast C implementations. The best part? All your existing code keeps working exactly as before - no API changes,…
We also had Serhiy Storchaka working on Base64 compliance, making sure our decoder properly follows RFC 4648 standards. It's one of those "under the hood" improvements that makes Python more reliable and predictable. These standards matter,…
Now,…
I'm…
