I am honestly lost on how to even begin to write code for this function based on the specification. They have a clue to use list.insert() but based on some of the examples how would you know what number needs to be replaced if the list can change? Here are some of my thoughts: can we save each number and use indexing then use insert?

Below is the function with specifications:

def rotate(alist): """ Rotates the contents of alist one element to the right. Rotating a list to the right pushes all elements to the right, and makes the previously last element the new first element. Examples: If a = [0,2,3,4], rotate(a) makes a = [4,0,2,3] if a = [0,1,3,5], rotate(a) makes a= [5,0,1,3] if a = [0,1,3,5], rotate(a) makes a= [1,3,5,0] if a = [0,1,3,5], rotate(a) makes a= [0,1,3,5] If a = [1], rotate(a) makes a = [1] Parameter a: The list to rotate Precondition: a non-empty list """ # Hint: Read the method description for insert
