Will Airflow 2.0.0 support Python 2.7?

[airflowuser <ai...@protonmail.com.INVALID>]

Are there plans to drop support for Python 2.7 - if so when ?

I think we should probably drop Python2.7 support for 2.0 since it will be
quite a large undertaking and I expect it to take a long time to complete
since we should batch as many as the non-backwards incompatible changes we
want to make as possible. Even if we drop support a little bit earlier than
Jan 1 2020 I don't think it's the end of the world (since users can just
use older package versions).

For what it's worth I do not think you are wrong.

Given that we are definitely depending on a large ecosystem of packages,
some of which might drop support next year, it might make sense to at least
announce deprecation in 2.0 and deprecate in 3.0.

3.0 could happen early 2020 though.

Best,
Arthur

I think that many packages dropped support for Python 2.7 because they are depend on 3rd party packages which also dropped support.

Python 2.7 will be deprecated on 1-Jan-2020.
Assuming Airflow 2.0.0 will be released 1st/2nd quarter of 2019 it means that airflow 3.0.0 will have to be introduced 3rd/4th of 2019 quarter as dropping support for Python 2.7 can't be done in minor version...

Am I wrong?

This came up previously, and no firm conclusion was released, but given Python 2.7 is still maintained for another year, yes, probably.
