Apache Spark Certification Practice Test

Question: 1 / 400

True or False: The pySpark shell automatically creates the sc variable.

True

The statement is true because when you start the PySpark shell, it initializes a SparkContext object and assigns it to the variable named `sc`. This automatic creation of the `sc` variable allows users to easily interact with the Spark environment directly without needing to explicitly create a SparkContext themselves each time they start a session.

This behavior is standard in the PySpark shell, facilitating immediate access to Spark's features and functions for processing data. While there are different environments where PySpark can be executed, the automatic creation of the `sc` variable is a core feature of the PySpark shell itself, distinguishing it from other platforms or custom setups where users might need to initialize their context manually. This makes it easier for developers and data scientists to begin working with Spark without additional setup steps.
