I have found a hacky[1] but somewhat not too ugly way to dynamically use
any available python interpreter.

Basically, the scripts shebangs become:

 #!/bin/sh
 # shell script hack to dynamically use any available python interpreter
 ''':'
 if command -pv python3 >/dev/null 2>&1; then
   exec python3 "$0" "$@"
 else
   exec python2 "$0" "$@"
 fi
 '''
 # real python code starts here

This hack obviously would remain only for the time where we still have
python 2 support and can be removed after 20.08 is released.

What do you think?
