File Analysis Program code:

def compareBothFiles(firstFilePath, secondFilePath):
    # Read the contents of the first file
    with open(firstFilePath, 'r') as file1:
        contents1 = file1.read()

    # Read the contents of the second file
    with open(secondFilePath, 'r') as file2:
        contents2 = file2.read()

    # Split the contents of each file into individual words
    words1 = set(contents1.split())
    words2 = set(contents2.split())

    # Display a list of all unique words contained in both files
    uniqueWords = words1.union(words2)
    print("Unique Words in Both Files:")
    print(uniqueWords)

    # Display a list of words that appear in both files
    common_words = words1.intersection(words2)
    print("\nCommon Words in Both Files:")
    print(common_words)

    # Display a list of words that appear in the first file but not the second
    uniqueWords_file1 = words1.difference(words2)
    print("\nWords in File 1 but Not in File 2:")
    print(uniqueWords_file1)

    # Display a list of words that appear in the second file but not the first
    uniqueWords_file2 = words2.difference(words1)
    print("\nWords in File 2 but Not in File 1:")
    print(uniqueWords_file2)

    # Display a list of words that appear in either the first or second file but not both
    exclusive_words = words1.symmetric_difference(words2)
    print("\nWords Exclusive to Either File:")
    print(exclusive_words)


# Usage example
firstFilePath = "firstFileData.txt"  # Replace with the path to your first text file
secondFilePath = "secondFileData.txt"  # Replace with the path to your second text file
compareBothFiles(firstFilePath, secondFilePath)
