Changing your Python version with Anaconda
Python 3 is the future and the future is now. Considering best practise, the way forwards is to move with the times and upgrade. To make the change over easier, here’s a cheat sheet for writing python 2/3 compatible code. HOWEVER, when all of your scripts are written in a Python 2.x way, maybe now isn’t the time to move on… having a load of v2.x / v3.x errors can be inconvenient to say the least.
I’m not saying that you should, I’m simply showing how you could downgrade your python version if using Anaconda.
Downgrading between versions is easy if you are using an Anaconda Python distrib. By going on to the command line, it is possible to quickly search for available versions and upgrade/downgrade accordingly.
Step-by-step downgrade/upgrade

Search for available versions - can search for what you want, but we’ll look for “python”

To change your python version, you can now just type:
conda install python=3.5.0 # or maybe conda install python=2.7.8 # or whatever you want....
