# Learn Recursion by Solving the Tower of Hanoi Puzzle - Step 31

### Tell us what’s happening:

Would someone be able to help me with this please? I’m not sure how much of the code needs to be moved here and nothing I try seems to work, just brings up the code cannot be read response. I tried it in a repel and it seemed fine

``````NUMBER_OF_DISKS = 3
number_of_moves = 2**NUMBER_OF_DISKS - 1
rods = {
'A': list(range(NUMBER_OF_DISKS, 0, -1)),
'B': [],
'C': []
}

# User Editable Region

def make_allowed_move(rod1, rod2):
forward = False
if not rods[target]:
forward = True
elif rods[source] and (not rods[target] or rods[source][-1] < rods[target][-1]):
forward = True
return forward

def move(n, source, auxiliary, target):
# display starting configuration
print(rods)
for i in range(number_of_moves):
remainder = (i + 1) % 3
if forward:
print(f'Moving disk {rods[source][-1]} from {source} to {target}')
rods[target].append(rods[source].pop())
else:
print(f'Moving disk {rods[target][-1]} from {target} to {source}')
rods[source].append(rods[target].pop())

# display our progress
print(rods)

# User Editable Region

elif remainder == 2:
print(f'Move {i + 1} allowed between {source} and {auxiliary}')
elif remainder == 0:
print(f'Move {i + 1} allowed between {auxiliary} and {target}')

# initiate call from source A to target C with auxiliary B
move(NUMBER_OF_DISKS, 'A', 'B', 'C')

Move the code nested inside the first `if` statement (except the first `print()` call) to your new function.
Move all of this. Everything after this print line is indented, and therefore nested within the `if` statement:
