Please do the following in Python 3. Please comment your code so I understand what is going on.

Write a function that receives a collection of strings and a map from strings to integers. Return a collection of integers that are values of the map corresponding to one of the strings in the collection. For example, given Array("Tom", "Dick", "Harry") and Map("Tom" -> 3, "Fred" -> 4, "Harry" -> 5), return Array(3, 5). (The array and map are pseudo-code to let you know the types.)
