[docs] [issue20068] collections.Counter documentation leaves out interesting usecase

[Raymond Hettinger]

Raymond Hettinger added the comment:

The introductory example already shows both ways of using a Counter:

1) How to tally one at a time:

   cnt = Counter()
   for word in ['red', 'blue', 'red', 'green', 'blue', 'blue']:
       cnt[word] += 1

2) How to count directly from a list:

    words = re.findall(r'\w+', open('hamlet.txt').read().lower())
    Counter(words).most_common(10)
