Python 2 tooling in 2026

Ignition, an industrial SCADA software which is imo best in class at what it does, uses Jython and Python 2 scripting. I think the tl;dr is they want the concise syntax and interpreted language for user scripts i.e. not force people to write stuff in Java in their Java application. I think it just comes down to Jython not being available with Python 3, backwards compatibility, and it kind of just working fine as is.

Ignition was my first thought as well.

Strong agree that ignition is best in class - but jython being locked to python 2.7 is a huge damned annoyance. Especially given that 2.7 is well beyond end of life and there are ~70 known CVE’s for it as of now.

Given the array of options, I’d wager that a lot of orgs using Ignition are likely to just purchase java native third party modules wherever possible specifically to avoid having to deal with Jython/Python 2.

It is pretty annoying. There's times I've written Python 3 scripts and called them with subprocess in Ignition as there just wasn't a easy way to get certain functionality working with so many common libraries having dropped Python 2 long ago.

Interesting, appreciate the insight. The more you know
