Spark SQL is a Spark module for structured data processing. Unlike the basic Spark RDD API, the interfaces provided by Spark SQL provide Spark with more information about the structure of both the data and the computation being performed.
"If you have 2 or more python 3.X.x versions, you will only see the latest one." Won't it instead show whichever one has its containing directory listed first in the PATH environment variable? Why would running python3 always run the highest (sub)version of python3 that is installed?

The guidelines provided here are intended to improve the readability of code and make it consistent across the wide spectrum of Python. I have JSON data stored in the variable data. I want to write this to a text file for testing so I don't have to grab the data from the server each time.
Currently, I am trying this: obj = open. Many users write either automation scripts directly against the OpenStack Representational State Transfer (REST) application programming interface (API) or shell scripts that invoke the command-line tools (for example, keystone or nova).But a better way exists to write OpenStack automation scripts in Python.Download
