No it isn’t.

One of the issues with Python 3 is that there isn’t really one killer feature, it’s countless little ones. Many believe 3.6 was the first release where they added up to enough of a benefit (though f-strings are a big help for many projects).

Regardless it no longer matters, the Python 2 ecosystem is now rotting as packages drop support. Every week I have to make one or two hot fixes somewhere to forcibly pin to an old version to fix something.

For me, proper handling and distinction of Unicode vs. binary data was a game changer. I don't know if that's related to my first language being non-English, but I remember it being really important to me and a strong reason why I made the switch years ago.

I used to work for a huge SEM business working with keywords in all languages of the world. No-brainer.

I would definitely mention integer division as a massive change in py3 too. In my field, the @ multiplication operator is also useful.

To be fair, you can get that in Python 2 too:

  from __future__ import division
