Thank goodness there was 2to3 tool in the past. It made the migration to Python 3 so smooth and quick. /partial-s

I know it is not nearly on the same level, but people seriously overestimate the effort needed between not doing anything at all and even the slightest work, no matter how reliable and easy. The difference between nothing and anything is huge.

I feel like I've heard this argument countless times, and yet I'm never swayed by it. I've been using Python for about 20 years and I've never felt put out by the need to change anything to work with a new version of Python (or of a library). It simply hasn't caused significant pain - my memories are more filled with painful debugging sessions caused by overly-clever designs or trying to refactor too much at once.
