Please make sure you adhere to the policies on academic integrity.

1. (6 points)

   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]).

2. (6 points)

   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.)

3. (8 points)

   On our recent exam there was a question that involved converting a phrase such as 'laughing out loud' to an acronym such as 'LOL'. (Actually, the question was to use a loop to do this converstion for many different phrases, but we will focus on a single phrase for this question.)

   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.
