Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares (nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num num) return result If the main program calls print (squares ( [5, -3, 2, 7])) what is the state table for the function squares after the for loop has completed exactly 3 iterations?
