Hello!

Just wanted to comment the biggest difference between Python and Jython I found in perspective is the f-string (f") to format a string. This doesn´t allow the code to compile , other than that I haven´t found many differences.

In the future Jython may admit f"?

Cheers

There are many differences, because Jython uses Python 2 syntax.

There may come a day when Jython supports python 3 syntax, but I wouldn’t hold my breath.

AFAIK it's basically dead in the water? I don't think outside of Ignition developers there's a large demand for jython to be updated.
