How do I execute Cassandra CLI commands from a Python script?

Question

I have a python script that I want to use to make remote calls on a server, connect to Cassandra CLI, and execute commands to create keyspaces. One of the attempts that I made

Answer 1

try this out. I don't have cassandra-cli installed on my machine, so I couldn't test it myself.

from subprocess import check_output
from tempfile import NamedTemporaryFile
CASSANDRA_CMD = 'cassandra-cli -host localhost -port 1960 -f '

def cassandra(commands):
    with NamedTemporaryFile() as f:
        f.write(';\n'.join(commands))
        f.flush()
        return check_output(CASSANDRA_CMD + f.name, shell=True)

cassandra(['CREATE KEYSPACE someguy', 'exit'])

As you mentioned in the comment below pycassa a Python client for Cassandra cannot be used since it doesn't seem to support create statements.
