So this code is working and all but I do not understand exactly what is going when I use it. Would gladly appreciate an explanation of how this code is working.

def towers_of_hanoi(n, start, end):
    """Print the moves required to solve the towers of hanoi game, starting
    with n disks on the start pole and finishing on the end pole.

    The game is to assumed to have 3 poles.

    >>> towers_of_hanoi(1, 1, 3)
    Move the top disk from rod 1 to rod 3
    >>> towers_of_hanoi(2, 1, 3)
    Move the top disk from rod 1 to rod 2
    Move the top disk from rod 1 to rod 3
    Move the top disk from rod 2 to rod 3
    >>> towers_of_hanoi(3, 1, 3)
    Move the top disk from rod 1 to rod 3
    Move the top disk from rod 1 to rod 2
    Move the top disk from rod 3 to rod 2
    Move the top disk from rod 1 to rod 3
    Move the top disk from rod 2 to rod 1
    Move the top disk from rod 2 to rod 3
    Move the top disk from rod 1 to rod 3
    """
    assert 0 < start <= 3 and 0 < end <= 3 and start != end, "Bad start/end"
    "*** YOUR CODE HERE ***"
    if n==1:
        print("Move the top disk from rod", start, "to rod", end)
    else:
        towers_of_hanoi(n-1, start, 6-end-start)
        towers_of_hanoi(1, start, end)
        towers_of_hanoi(n-1, 6-start-end, end)
