PySpark and AWS: Master Big Data with PySpark and AWS - Quiz (Word Count) - Spark DFs

This video tutorial introduces a quiz where students use a file named 'word data.txt' as input. The task involves reading the file into a data frame and calculating the word count for each word present. The instructor provides a hint about the file's structure, noting the absence of a header.
