Python 3 was introduced two and a half years ago. Its major syntactic changes, while frustrating if you're set in your ways, are hardly insurmountable.

This. Most of the time I run into an issue with a change I wasn't aware of, a quick search through the 3.X docs just points me in the right direction.

I think it's fine if you're doing python all day long, but I'm using Python, Java, PHP, Obj-C and Javascript each at least once a month on a variety of paid and personal projects. Like I said, I have enough trouble keeping those syntaxes straight.
