Using reduce together with map

# The total number of characters in a list of words
def demoReduce(yesOrNo):
  if yesOrNo == 1:
    return totalNumCharactersUsingReduce(cheeses)
  else:
    return totalNumCharactersUsingLoop(cheeses)

def totalNumCharactersUsingLoop(wordList):
  totalNumOfChars = 0
  for word in wordList:
    totalNumOfChars += len(word)
  return totalNumOfChars

# We go through the list of word lengths (compare demoMap)
def totalNumCharactersUsingReduce(list):
  return reduce(add, map(len, list))

def add(a, b):
  return a+b
