It should be installed as either python3 or python3.4. To figure out which, type 'python' in the terminal, and hit tab twice. It should bring up a list of python interpreters you have installed. > (2) Do I need to uninstall Python 2.7.3 (if so, how do I go about doing this) > before setting a global environmental variable such as PYTHON_HOME to the > location of the installed Python 3.4.3? You don't need to uninstall python 2.7, and you shouldn't try. I tried it as an experiment at one time, and my system had various mysterious failures after that. It may be that Yosemite fixes those failures, but I wouldn't bet on it. Thanks, Cem Karan -- https://mail.python.org/mailman/listinfo/python-list
