In a legacy system, directions are stored by magnitude followed by direction. Thus, "12E" represents " travel 12 kms towards east, "4N" represents 4kms to the north, "120S" represents 120 kms south and finally "3W" represents 3 kms towards west. Given a list that holds a collection of individual directions, return how far from the starting point will we be. You can use int(string) to convert a string to an integer, provided it can be converted. You will also need String functions such as string[index] and string[start:end]. distanceFromHome(["10N", "10W", "10S", "10E"]) → 0.0 distanceFromHome(["10N", "10W", "10S", "8E"]) → 2.0 distanceFromHome(["8N", "6W"]) → 10.0
