In Ubuntu, all python packages use explicit python3 or python2 interpreter and do not use unversioned /usr/bin/python at all No packages may declare dependencies on this package. So, all official Ubuntu packages will depend explicitly on “python2” or “python3”, and invoke the appropriate command.
Ubuntu has already moved almost all of its projects from Python 2 to Python 3. For example, according to release notes of Disco Dingo: Samba was updated to version 4.10.x, and one of the big changes here is python3 support.
By default, both python2 and python3 are installed. This will only show the version of python2, while on 14.04, python3 is installed as well. To see the version of python3, simply replace all occurrences of python in the commands above by python3 will make python 3 run it, and (if the script is executable), the shebang.

Where do programs get installed ubuntu?
There’s still a set of ‘standard’ locations that programs are put into. For example, binaries (in windows parlance ‘ executables’) are put in /usr/bin, and documentation is put in /usr/share/doc in a Ubuntu system. This is a pretty simplistic answer.
But the general idea is that the /bin and /usr/bin are where the start up application files (executables or scripts) are stored .
