Anaconda Python distribution

We use the Anaconda distribution to run Python 3, as it is easy to install and comes with most packages we need. To install Anaconda, go to the linked url and get the Python installer for your OS - make sure to use the newer version 3.x, not 2.x. Follow the instructions of the installer and you're done.

Warning! The installer will ask you if you want to add Anaconda to your path. Your default answer should be yes, unless you have specific reasons not to want this.
