Tell us what’s happening:

I found a similar problem and read the forum, but I don’t have his problem,
in the terminal, I have my answer displayed correctly,
I can’t find the bug

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 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}')

# initiate call from source A to target C with auxiliary B
