Choosing a Python Version

We use Anaconda as our default python distribution.

There are 3 versions to choose from

  1. latest - python 3.6 or latest
  2. python 3.5
  3. python 2.7

To see all avilable environments

    $   conda info -e

Output may look like

# conda environments:
py27                     /opt/conda/envs/py27
py35                     /opt/conda/envs/py35
root                  *  /opt/conda

To choose a version

    ## source activate <VERSION>
    $   source activate py27

    ## verify
    $   conda info -e

Selected environment will have '*' next to it

# conda environments:
#
py27                  *  /opt/conda/envs/py27
py35                     /opt/conda/envs/py35
root                     /opt/conda

To 'deactivate' the environment

    $  soure deactivate
