Hints:

• Use an accumulator to build up the list.

• To add a new random number to the list, you may either use string concatenation (as we have done before), e.g.,

      lis = [42, 915]
      lis = lis + [707]
      lis --> [42, 915, 707]
  

  or the list append() method suggested in the problem.

  list.append One argument: Any Python3 value State change: The value arg1 is added as a new element at the end of a list object. Return: None

  Example call:

      lis = [42, 915]
      lis.append(707)
      lis --> [42, 915, 707]

Here is a spec.

count5Words One argument: A Python 3 list of strings Return: A non-negative integer, the number of elements of arg1 that have length five.

Example calls:

    count5Words(['apple', 'banana', 'cherry', 'grape']) --> 2
    count5Words([]) --> 0
