It's pretty easy to avoid such issues: pick one Python instance of each 
version (2 and 3) and stick with it, be it one of the system-supplied 
Pythons, a Python, or a third-party Python like from 
MacPorts, homebrew, Anaconda, et al.  In that respect, OS X is no 
different than any Linux distribution.

It's good to be cautious but better to be "informed cautious".  Public 
betas have been available since July; developer previews before that.  
And, while Apple has not announced an official release date yet, they 
have said "Fall 2014" and, given the history of recent OS X releases and 
the current rumor mill, one would be advised to not bet against an 
October release date.

Let's just say that I will personally be *very* sad if 2.7.8 and 3.4.2 
don't work as well or better on 10.10 as they do on 10.9.x and earlier 
supported OS X releases.
