Six is a Python 2 and 3 compatibility library. It provides utility functions for smoothing over the differences between the Python versions with the goal of writing Python code that is compatible on both Python versions.
To install the python-six package from the default Ubuntu 16.04 repositories:
sudo apt install python-six
To install six globally with pip, open the terminal and type:
sudo -H pip2 install --upgrade pip
sudo pip install six
To install six locally with pip (e.g. in a Python virtual environment):
python -m pip install --upgrade pip
python -m pip install --user six
