Thanks for your quick reply. The code in cqlsy.py states it supports python 2.7
AND python 3.x, but 2.7 its deprecated, unless I'm misreading it.
if sys.version_info < (3, 6) and sys.version_info[0:2] != (2, 7):

sys.exit("\ncqlsh requires Python 3.6+ or Python 2.7 (deprecated)\n")
and the cqlshlib imports 'six' for cross-compatibility instead of using native
python 3.x constructs.
If the intention is to no longer support python 2.7, the above should be simply
changed to exit if sys.version_info is less than 3.6
if sys.version_info < (3, 6):

> Remove Python 2.x support from CQLSH
> ------------------------------------
>
> Key: CASSANDRA-17242
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17242
> Project: Cassandra
> Issue Type: Task
> Components: CQL/Interpreter
> Reporter: Brad Schoening
> Priority: Normal
> Fix For: 4.0.x, 4.x
>
>
> Python 2 has now reached EOL and should be removed from CQLSH and other
> Cassandra components.
> "We are volunteers who make and take care of the Python programming language.
> We have decided that January 1, 2020, was the day that we sunset Python 2.
> That means that we will not improve it anymore after that day, even if
> someone finds a security problem in it. You should upgrade to Python 3 as
> soon as you can.
> And if many people keep using Python 2, then that makes it hard for [the
> volunteers who use Python to make
> software|https://python3statement.org/#sections50-why]. They can't use the
> good new things in Python 3 to improve the tools they make.
> As of January 1st, 2020 no new bug reports, fixes, or changes will be made to
> Python 2, and Python 2 is no longer supported.
> "
