Is Python 2.7 mandatory to install DSE 6.7 on Debian-based systems?

Hey Guys:
Can I have Python 3.* while installing DSE 6.7? Or is it mandatory to have 2.7.x as mentioned in the prereqs?

> Python 2.7.x

DSE 6.7 doc has the following:
> CQLSH can be run with Python 2 or 3. The Python 3 support is new. (DB-4151)

So I was wondering if having Python 2.x is a strict requirement

You are correct. You can use either Python 2.7 or 3.6+.

Thanks for bringing this up. It was an oversight on our part to have the documentation reflect the change. I've logged a request to have the Docs updated (internal request ID DB-4673).

For what it's worth, you can install DSE regardless of whether Python is installed or not. It is only required if you intend to run cqlsh on a node. Cheers!

Looks like DSE installation installs Python 2.7v as well.

The following additional packages will be installed:  
libopts25 libpython-stdlib libpython2.7-minimal libpython2.7-stdlib ntp python python-minimal python2.7 python2.7-minimal sntpSuggested packages:  ntp-doc python-doc python-tk python2.7-doc binutils binfmt-support
