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.

As CTO at my previous company, I had to veto developers who wanted to migrate from Python 2 to Python 3. The amount of effort required for the migration and the fairly low chance of a trouble free switch just didn't make a good business case for a working codebase that brought in millions in revenue each year and paid all of our salaries. All new development was in Python 3. But existing running code just had too high a risk and too low a reward for migrating.

You really ought to migrate. Old code that doesn't get security updates is a bad risk
