Hmm... I guess I haven't given you enough spells for this one yet after all!
You can do another FIND call where you start looking at a specified index.
firstSpaceIndex = name.find(" ")
secondSpaceIndex = name.find(" ", firstSpaceIndex + 1)
Or you could use rfind() to find backward from the end (right side):
secondSpaceIndex = name.rfind(" ")
However, these approaches may fail if there are multiple spaces separating between the names...
BETTER APPROACH: You could solve this problem using the split method, which splits a string into a list of smaller strings based on a separator string, which we'll talk about in class tomorrow.
nameParts = name.split(" ")
nameParts will be a list containing the first, middle, and last names as separate strings. We can index lists similar to how we index strings...
firstName = nameParts
