Hands-On Convolutional Neural Networks with TensorFlow

Doing queries in Python

First, before we start playing around, we need to install the Python driver pip install cassandra-driver​; the following snippet of code just lists the content of a table in the Cassandra cluster:

from cassandra.cluster import Cluster​ 
import cassandra.util​ 
import uuid​ 
import numpy as np​ 
​ 
# Considering that the cluster is on localhost​ 
cluster = Cluster()​ 
# Other option if you know the IPs​ 
# cluster = Cluster(['192.168.0.1', '192.168.0.2'])​ 
# Get a session to the database​ 
session = cluster.connect('mydb')​ 
​ 
# Doing a query​ 
rows = session.execute('SELECT * FROM tb_drive limit 5')​ 
print('Columns:',rows.column_names)​ 
for row in rows:​ 
    print(row.id, row.acc, row.wheel_angle)
