Of the 50 /usr/bin/ python files on my Ubuntu 16.04 desktop, most are versioned in some way. None are called from "env".

     37 /usr/bin/python3
      4 /usr/bin/python3.5
      4 /usr/bin/python
      3 /usr/bin/python2.7
      2 /usr/bin/python2

The 4 that aren't versioned are

speedtest, speedtest-cli, dh_python2, apt-offline

So two from ubuntu/debian, and two from a package
