Ask HN: Time to start using Python 3.x?

For class - yeah, definitely use Python 3. There's basically no downside to this - you'll write your project and never touch it again after 4 months, and in the meantime you'll have gained valuable experience for yourself as to whether you should use Python 3 for future projects.

The folks who should pause before using Python 3 are those who have to maintain legacy systems that need to interface with libraries that may or may not support it.

Noted. Thanks.

Flask supports Python 3, but a lot of its plugins don't, according to http://flask.pocoo.org/docs/python3/.

I am using Python 3.3 for my startup, and I never have to look back yet. I think you should go for Python 3 for class.

Thanks. What's your startup?

If the libraries you need are all ported, absolutely.
