Right you are Kay. It would be very weird to start developing things on Python 2.7 right now. Its days are numbered: https://pythonclock.org/ Cheers, Robbie Sent from my Windows 10 phone ________________________________ From: CCP4 bulletin board <[log in to unmask]> on behalf of Kay Diederichs <[log in to unmask]> Sent: Wednesday, June 6, 2018 8:47:07 PM To: [log in to unmask] Subject: Re: [ccp4bb] Python3 and MTZ Dear Nicolas, my (our) motivation is purely that when learning Python today, and developing something from scratch, Python3 appears like the better choice (compared to version 2) - provided that basic crystallographic libraries can be used. Just a note (for those whose operating system provides only one of the two Python flavours): RHEL7 has Python2 as system library, but Python3 can be installed in parallel (using "Software Collections"). The user makes a choice by setting the PATH variable. best, Kay On Wed, 6 Jun 2018 15:43:16 +0200, Nicolas FOOS <[log in to unmask]> wrote: >Dear Kay, > >depending of the motivation to develop in python3 (could be due to an OS >using python3 by default or you really prefer to work with python3).
