-Function which accepts a dictionary of key value pairs and returns a new flat list of only the values.
 
-Uses the .items() function with a for loop on the dictionary to track both the key and value of the iteration and returns a new list by appending the values to it. Best used on 1 level-deep key:value pair dictionaries and not nested data-structures.
+Returns a flat list of all the values in a flat dictionary.
+
+Use `dict.values()` to return the values in the given dictionary.
+Return a `list()` of the previous result.
