Part 1: Create a DataFrame from CSV file

Every 4 years, soccer fans throughout the world celebrate a festival called “Fifa World Cup” and with that, everything seems to change in many countries. In this 3 part exercise, you'll be doing some exploratory data analysis (EDA) on the "FIFA 2018 World Cup Player" dataset using PySpark SQL which involves DataFrame operations, SQL queries, and visualization.

In the first part, you'll load FIFA 2018 World Cup Players dataset (Fifa2018_dataset.csv), which is in CSV format, into a PySpark's dataFrame and inspect the data using basic DataFrame operations.

Remember, you already have a SparkSession spark and a variable file_path available in your workspace.
