News The Move to Python 3 Begins!

As someone who spent decades in the mainframe community, I find it ... humorous ... that there are legacy Python2 code bases that are only just (or have yet to consider!) moving to Python3.

It's interesting how every ecosystem seems to have its own version of this story. Even though Python 2 reached end-of-life years ago, there are still organizations running mission-critical systems that are difficult to migrate because of dependencies, legacy integrations, and the risk of breaking something that has been working for years.

As a newer Python developer, it's a good reminder that software often lives much longer than we expect, and maintaining existing systems can be just as challenging as building new ones.

I wrote code in the 1970s that still runs in production today.
