I use IPython notebooks and would like to be able to select to create a 2.x or 3.x python notebook in IPython.
I initially had Anaconda. With Anaconda a global environment variable had to be changed to select what version of python you want and then IPython could be started. This is not what I was looking for so I uninstalled Anaconda and now have set up my own installation using MacPorts and PiP. It seems that I still have to use
port select --set python <python version>
to toggle between python 2.x and 3.x. which is no better than the anaconda solution.
Is there a way to select what version of python you want to use after you start an IPython notebook, preferably with my current MacPorts build?
