I'll go further than the other commenters: starting a brand new project in python 2 at this point is engineering malpractice.

Definitely. Python 2 is EOL and will no longer be getting updates. The upgrade is easy, especially if you don't have much code written.

switching isn't just worth it, I would say its mandatory.

there has been no reason now for years to start any new project in python2, and since it went EOL last year you would have to be crazy to use it.

Python 2 is end of life. Python 3 should be the only option for new projects. Python 3 is great.

Yes, starting something new in 2.x really doesn't make sense anymore outside very very special circumstances.

If you're considering switching languages, maybe consider other options outside the Python family as well.

Yes. Python2 will get harder and harder to maintain as a dependency. You're fighting the whole ecosystem at this point.
