Description

Users who operate in a Python 3 environment may have trouble launching cqlsh. Could we please update cqlsh's syntax to run in Python 3?

As a workaround, users can setup pyenv, and cd to a directory with a .python-version containing "2.7". But it would be nice if cqlsh supported modern Python versions out of the box.
