# Learn Recursion by Solving the Tower of Hanoi Puzzle - Step 52

### Tell us what’s happening:

NUMBER_OF_DISKS = 4
A = list(range(NUMBER_OF_DISKS, 0, -1))
B =
C =

def move(n, source, auxiliary, target):
if n > 0:
# move n - 1 disks from source to auxiliary, so they are out of the way
move(n - 1, source, target, auxiliary)

``````    # move the nth disk from source to target
target.append(source.pop())

# display our progress
print(f"{A},{B},{C}\n")

# move the n - 1 disks that we left on auxiliary onto target
``````

NUMBER_OF_DISKS = 4
A = list(range(NUMBER_OF_DISKS, 0, -1))
B = []
C = []

def move(n, source, auxiliary, target):
if n > 0:
# move n - 1 disks from source to auxiliary, so they are out of the way
move(n - 1, source, target, auxiliary)

# move the nth disk from source to target
target.append(source.pop())

# display our progress
print(f"{A},{B},{C}\n")

# move the n - 1 disks that we left on auxiliary onto target
move(n - 1, auxiliary, source, target)

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

Need help, please with printing the output, I dont know if I'm missing something

We see you have posted some code but did you have a question?

If you look at the original code it prints the `rods` variable and it’s not an f-string:

``````print(rods, '\n')
``````

not

``````print(f"{rods}\n")
``````

Got it, thanks a lot
