   Assume that tokens is a list of strings read from a text file, that represent numeric values (e.g., ['23', '35', '8', '200']).

   Give a single line that uses comprehension syntax to produce a new list, named vals, which are the corresponding integer values (e.g., [23, 35, 8, 200]).

   Assume that nouns is a list of strings. Given a line that produces a new list, plural, containing all of the original words that end with the character 's'. (Yes, I realize that these might not actually represent plurals, but this is just an exercise.)

   Consider the goal of creating an acronym for a phrase by capitalizing the first letter of each word, such as the acronym 'LOL' for the phrase 'laughing out loud'. We could accomplish the goal using traditional techniques as in the following:

   initials = []
   for word in phrase.split():
       initials.append(word[0].upper())
   acronym = ''.join(initials)
   

   Your task is to give a single line of code of the form

   acronym = ???

   that accomplishes the above task.
