linux switch between ananconda python 3.4 and 2.7

Question

I do most of my work in Python 2.7, but I've recently encountered some tutorials that require 3.4. Fine. I checked and Anaconda allows installation of both under Linux (Fedora 22 to be precise). However, now I seem to be stuck in 3.4. I followed the Anaconda directions, entering: conda create -n py3k python=3 anaconda source activate py3k I would like to be able to choose between 2.7 and 3.4 each time I run Python. Any ideas?

Answer 1

I think I can answer my own question. Python 2.7 seems to be the default. If I activate 3.x with source activate py3k I need to reboot to go back to 2.7, which, being the default, happens automatically.

If anyone knows a cleaner way, please let me know.
