So, all is well so far. Note that during the install of anaconda, the dialog had the two questions Sage Wall mentions, with a slight modification, in that it actually asked: "make Anaconda the default Python 3.5", and not the "default Python", so I kept this box ticked, because the anaconda Python 3.5 is the only 3.5 Python that I have installed (the others are 2.7.5). No issues so far.
