Currently running Mac OS X Lion 10.7.5 , and it has python2.7 as default. In the terminal, i type \'python\' and it automatically pulls up python2.7. I don\'t want that.
If you have python 2 and 3 on brew. Following worked for me.
brew unlink python@2
brew link python@3 (if not yet linked)
brew link python@3
