wishing for a 3-way loop construct

[cathodion]

I'm a little late with this reply, but enumerate() might be a good way to do it.  Can't post a clickable link, but it's one of the built-in functions and returns an iterable of tuples like (index, item).

words = "the quick brown fox jumped over the lazy dog".split()

def isFirstIndex(index, lst):
    return index == 0 

def isLastIndex(index, lst):
    return index == len(lst) - 1 

for i, word in enumerate(words):
   if isFirstIndex(i, words):
       print(word.upper(), end=' ')

   elif isLastIndex(i, words):
       print(word[::-1] + '.')

   else:
       print(word, end=' ')

Output:
THE quick brown fox jumped over the lazy god.
