What's the default Python 3 version in the new Ubuntu 20.04? Is it still 3.6 or the latest Python 3.8?

I'm developing a Python program that I later want to run on the new Ubuntu 20.04. I'm unsure if I can use the latest Python 3.8 syntax. I don't have Ubuntu 20.04 installed yet to quickly check it, and I couldn't easily find the answer to this question on Google.

According to the Ubuntu 20.04 release notes:

Ubuntu 20.04 LTS comes with a refreshed state-of-the-art toolchain including new upstream releases of glibc 2.31, OpenJDK 11, rustc 1.41, GCC 9.3, Python 3.8.2, ruby 2.7.0, php 7.4, perl 5.30 and golang 1.13.

Manifest file

Another thing you can do for any Ubuntu version and any package is to check the manifest file which lists all preinstalled packages in the image: https://web.archive.org/web/20200508223720/https://releases.ubuntu.com/20.04/ubuntu-20.04-desktop-amd64.manifest

It contains python3.8 but nothing that seems python2 related.

If you want to find the default Python 3 version of any Ubuntu release, you can run the command

rmadison python3
 python3 | 3.2.3-0ubuntu1   | precise         | all
 python3 | 3.2.3-0ubuntu1.2 | precise-updates | amd64, armel, armhf, i386, powerpc
 python3 | 3.4.0-0ubuntu2   | trusty          | amd64, arm64, armhf, i386, powerpc, ppc64el
 python3 | 3.5.1-3          | xenial          | amd64, arm64, armhf, i386, powerpc, ppc64el, s390x

 python3 | 3.8.6-0ubuntu1   | groovy          | amd64, arm64, armhf, i386, ppc64el, riscv64, s390x

Alternatively, check the package

https://packages.ubuntu.com/search?suite=groovy&keywords=python3

For groovy (Ubuntu 20.10), it's Python 3.8.6:

    A faster way of doing the same thing is to run the following command in a terminal: rmadison python3. In Ubuntu 20.04 it returns python3 | 3.8.2-0ubuntu2 – karel Oct 12 '20 at 11:31
