Use the following as a template, replace the print line with any work for moving the discs using your data structure. The code below just prints the necessary moves.

def hanoi(n, a='A', b='B', c='C'):
    """
    move n discs from a to c using b as middle
    """
    if n == 0:
        return
    hanoi(n-1, a, c, b)
    print a, '->', c
    hanoi(n-1, b, a, c)

hanoi(3)
