Tell us what’s happening:

followed instructions and have checked indentation many times, what am I doing wrong?

Your code so far

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):
    if not rods[target]:
        forward = True
    elif rods[source] and rods[source][-1] < rods[target][-1]:
        forward = True
    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())

def move(n, source, auxiliary, target):
    # display starting configuration
    print(rods)
    for i in range(number_of_moves):
        remainder = (i + 1) % 3
        if remainder == 1:
            print(f'Move {i + 1} allowed between {source} and {target}')
            forward = False
            

            # 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')

Hi there, welcome to fcc community.

Move the code nested inside the first if statement (except the first print() call) to your new function

That means moving the block of code from line 18 to line 31 to the new function.
