https://python3wos.appspot.com/ https://python3wos.appspot.com/ I'm seeing an awful lot of green there. Most of the things that are red (which might influence someone to use Python 2 on a greenfield project) have alternatives that are green.

Twisted? I still see that as a BIG python 2 Wall of Shame I mean Superpowers issue.

  It's too bad that the WoS isn't able to display things like partial-support (https://twisted.readthedocs.org/en/latest/core/howto/python3.html https://twisted.readthedocs.org/en/latest/core/howto/python3...).

    And I'm not sure about the fine-grained accuracy here. For example, NetworkX is listed green, but its graphic subsystem, according to their documentation, does not support Python 3. Also, Oath2 seems like a big one, and would exclude many other packages that might use it.

      It is all self-reporting based on the classifiers given to PyPI (NetworkX lists itself as supporting Python 3, Python3.2–Python3.4). It seems like both it and twisted would benefit from a Python3–partial classifier

  gevent is pretty popular too.

    I used guv recently (https://github.com/veegee/guv https://github.com/veegee/guv) and it worked really well.

      Looks interesting. First time I have heard about it. I will definitely have to check it out. Thanks for the link!
      - aidos 12y ago
        Hope it works for you! I found that it behaved exactly like Gevent for what I was doing (which I gave up on due to Dropbox rate limits). I've been looking at porting all the flask-websocket stuff over by using guv as a base. Haven't done anything other than reading codebases but it looks like it should make it easy.

Guido's keynote: https://www.youtube.com/watch?v=G-uKNd5TSBw https://www.youtube.com/watch?v=G-uKNd5TSBw 5000 packages converted, 55,000 to go. If you can't port until somebody else does, then projects that depend on you can't convert. Guido talks about this, and says more than "looks green to me".

Bloomberg's Open API is not on there and I think pretty much the only thing keeping me on 2.7. Don't know the ecosystem as well as others but imagine there will be more enthusiasm for 3.x in finance once that's done.

Some packages are ported but that does not mean people use Python 3. If you look at the download numbers it's pretty clear that they are not indicate actual use: https://caremad.io/2015/04/a-year-of-pypi-downloads/ https://caremad.io/2015/04/a-year-of-pypi-downloads/

the situation for greenfield projects is much better than it has been in past years. I would feel just fine about, for example, starting a new django web app in Python 3. however, the vast overwhelming vast huge vast majority of software in the world is legacy systems. software lifecycles are long and the cost of migrating from Python 2 to Python 3 is very high for those systems.
