Tell us what’s happening:

Describe your issue in detail here.

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):
    forward = False
    if not rods[target]:
        forward = True
    elif rods[rod1] and rods[rod1][-1] < rods[target][-1]:
        forward = True              
    if forward:
        print(f'Moving disk {rods[rod1][-1]} from {rod1} to {rod2}')
        rods[target].append(rods[ro1].pop())
    else:
        print(f'Moving disk {rods[target][-1]} from {target} to {rod2}')
        rods[rod2].append(rods[target].pop())
    
    # display our progress
    print(rods)

# User Editable Region

 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}')            
        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')

Don’t change the given code, just move it as the instructions say. For example, you changed the posted line above from the code line in this challenge:

  else:
          print(f'Moving disk {rods[target][-1]} from {target} to {source}')
          rods[source].append(rods[target].pop())

‘source’ vs ‘rod’ etc.

Reset the step.
Select the required code lines, cut them (Ctrl + X), and paste them instead of the ‘pass’ in the make_allowed_move function. Pay attention to the indentation.
