Learn Recursion by Solving the Tower of Hanoi Puzzle - Step 35

Describe your issue in detail here.
Hi team, for some reason I can’t go beyond this step. I think I indented as needed.

Your code so far

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

def make_allowed_move(rod1, rod2):    
    forward = False
    if not rods[rod2]:
        forward = True
    elif rods[rod1] and rods[rod1][-1] < rods[rod2][-1]:
        forward = True              
    if forward:
        print(f'Moving disk {rods[rod1][-1]} from {rod1} to {rod2}')
        print(f'Moving disk {rods[rod2][-1]} from {rod2} to {rod1}')
    # display our progress

def move(n, source, auxiliary, target):
    # display starting configuration
    for i in range(number_of_moves):
        remainder = (i + 1) % 3

/* User Editable Region */

        if remainder == 1:
            print(f'Move {i + 1} allowed between {source} and {target}')
            make_allowed_move(source, target)
        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}')
            make_allowed_move(source, auxiliary)

/* User Editable Region */

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

I think you missed this hint:
You should call make_allowed_move(source, auxiliary) inside the first elif clause.

No. Inside the second elif.

That hint shows up if you run the tests with your code. You are required to add a function call to each elif.

Understood. into each of them. Thank you.
