Three different Python versions? Ehh, no big deal. rosuav@sikorsky:~$ python2 --version Python 2.7.9 rosuav@sikorsky:~$ python3.4 --version Python 3.4.2 rosuav@sikorsky:~$ python3.5 --version Python 3.5.0b1+ rosuav@sikorsky:~$ python3.6 --version Python 3.6.0a0 rosuav@sikorsky:~$ pypy --version Python 2.7.8 (2.4.0+dfsg-3, Dec 20 2014, 13:30:46) [PyPy 2.4.0 with GCC 4.9.2] rosuav@sikorsky:~$ jython --version "my" variable $jythonHome masks earlier declaration in same scope at /usr/bin/jython line 15. Jython 2.5.3 And Steven D'Aprano probably can beat that by an order of magnitude. Keep your multiple interpreters around; it doesn't hurt. Unless you're seriously bothered by disk space issues, the biggest cost is keeping track of which one you've installed some third-party package into.
