There is no “default Python” in Debian. Python 2 and Python 3 are separate run-time systems, and are provided by different packages. > > $ apt-cache policy python The ‘python’ package is always Python 2. To find the default version of Python 3, you want the ‘python3’ package. > I just read Andrey's mail at > https://lists.debian.org/debian-python/2018/06/msg00024.html .

The ‘/usr/bin/python’ program is the Python 2 interpreter. There are no plans yet for that to change. The ‘/usr/bin/python2’ program is the Python 2 interpreter, and always will be. The ‘/usr/bin/python3’ program is the Python 3 interpreter, and always will be. There is no command in Debian for “the default Python”, because Python 2 and Python 3 are separate run-time systems that are not fully compatible. By using one of the above commands, you are explicitly declaring which Python run-time system to use. > To be more precise, I meant to know if 'Bullseye' i.e Debian 11 would > have python 3.0 as default or not. Bullseye will have both Python 2 and Python 3 available to install. I know of no plan to remove either of them in Bullseye. There is no “default Python” in Debian. To run a Python interpreter, you choose which major version you want to run; they are not meant to be compatible, and (as you pointed out) they are both in common use. So there is no default. I hope that helps clarify the issue. -- \ “Come on, if your religion is so vulnerable that a little bit | `\ of disrespect is going to bring it down, it's not worth | _o__) believing in, frankly.” —Terry Gilliam, 2005-01-18 | Ben Finney
