Loading CSV into DataFrame

In the previous exercise, you have seen a method for creating a DataFrame from an RDD. Generally, loading data from CSV file is the most common method of creating DataFrames. In this exercise, you'll create a PySpark DataFrame from the people.csv file that is already provided to you as a file_path and confirm the created object is a PySpark DataFrame.

Remember, you already have a SparkSession spark and a variable file_path (the path to the people.csv file) available in your workspace.
