Kelvintaph Pillars help pls ive been stuck on for so long

# Move the stack of peasants onto another stump.
# You can only carry 1 peasant at a time.
# You cannot stack a larger peasant onto a smaller peasant.
# You have access to the following APIs:
# pickUpItem(container) picks up the top/last item in a container.
# dropItem(container) drops the top/last (and only) item in you're carrying.
# You and the stumps have the following APIs:
# peekItem() returns the top item of the container.
# viewStack() returns an array of items in the container.
# Peasants have the following APIs:
# size; returns the size of the peasant

stump1 = hero.findByType("stump")[0]  # This is where the peasants start.
stump2 = hero.findByType("stump")[1]
stump3 = hero.findByType("stump")[2]


def move(frm, to):
    from_stump = [stump1, stump2, stump3][frm - 1]
    to_stump = [stump1, stump2, stump3][to - 1]
    
    hero.say("Moving from {} to {}".format(frm, to))
    hero.pickUpItem(from_stump)
    hero.dropItem(to_stump)


def hanoi(n, frm, to, via):
    if (n == 1):
        move(frm, to)
        pass
    else:
        pass
        hanoi(n - 1, frm, via, to)
        move(frm, to)
        hanoi(n - 1, via, to, frm)


hanoi(5, 1, 2, 3)

this line is wrong

  hero.say("Moving from {} to {}".format(frm, to))
