Problem 5 (4 pts.): Iterate over ar_list and print the name of each reviewer (author) and the total number of *different*, i.e. *unique*, words in his review. For example, "We stayed here and we liked it" contains 6 *unique* words since 'we' is repeated. [ ]: from collections import Counter import re for review in ar_lst: # TO DO: (1) Get the number of words in the current review variable. (2) Print the author's name and the number of (unique) words in his review Below are three approaches listed in increasing "sophistication". Three possible approaches... 1) Removing spaces between words and then counting uniques. gowharr32 used 91 unique words. Nancy W used 90 unique words. Janet H used 44 unique words.
