Take the list of words stored in the variable words and convert it into a datatype so that the new collection will only contain the unique words (i.e., no repetition, no duplicates).

a) store the unique words in a variable named unique_words.

b) Print out the number of unique words used in the paragraph. This could be used as one dimension of linguistic complexity of the paragraph.

words = ['i', 'had', 'a', 'fantastic', 'time', 'on', 'the', 'trip', 'how', 'was', 'your', 'day', 'would', 'you', 'like', 'to', 'go', 'to', 'the', 'ocean', 'tomorrow', 'it', 'will', 'be', 'fun', 'what', 'would', 'be', 'the', 'best', 'time', 'you', 'will', 'enjoy', 'watching', 'the', 'ocean', 'waves']
