What does
list.reverse()
Do

what does
list.sort()

variable = [[1,2,3,4],[5,6,7,8],[9,10,11,12]]
what code do you use to ask the user to enter the new figure (in the first column) into a 2D list
north = int(input(“Enter north figure: “))
what code do you use to ask the user to enter the new figure (in the last column) into a 2D list
south = int(input(“Enter south figure: “))
Why do we use variables
to keep track of counts and sums
why do we use iteration (for statements)
to iterate over strings of characters
