This question cannot be answered generically. I think it worth noting that in part this is the same dilemma as 'how many versions to support' within each of 2.x and 3.x. Limiting code to 3.3+ allows use of the new asyncio module (via Pypy for 3.3) and the new FSR unicode. Use of asyncio or FSR features* also forces the choice you give above as neither can be backported to 2.7. * IE, support of all of unicode on all Python systems with straightforward code, without contortions. If I were giving away 'stand-alone' application code whose dependencies were available on both 2.7 and 3.x+, I would write for 3.x+ on the basis that everyone could install 3.x, and that new users are increasingly likely to only have 3.x only. I would have little sympathy for organizations that prohibit 3.x -- unless they were to pay me to. For numerical or combinatorial code, adding 'from __future__ import division' (which I think one should do anyway for 2.x code) might be the only extra work needed for option 3). -- Terry Jan Reedy
