Anaconda Python Distribution
Anaconda is a pre-packaged Python distribution for scientific users. [1]
Direct your browser to
http://continuum.io/downloads.html ; download the version for your machine. Then follow the steps described for your machine here:
http://docs.continuum.io/anaconda/install.html. You do not need to worry about setting the paths yet.
By default, the Anaconda Python distribution uses Python 2.7 – we want Python 3.3. For this reason, we need to create a corresponding environment. In a shell (see below for opening one), go to the directory where you installed Anaconda.
On Windows, type:
cd Scripts
conda create -n py33 python=3.3 anaconda
On MacOS / Linux, type:
cd bin
./conda create -n py33 python=3.3 anaconda
Accept the list of things to be installed and wait for a bit. This will install an Anaconda Python environment based on Python 3.3 to the envs/py33 subdirectory of your Anaconda installation.
