Anyone please solve the step 25 of Learn Recursion

Python
1 
NUMBER_OF_DISKS = 3

number_of_moves = 2\*\*NUMBER_OF_DISKS - 1

rods = {
‘A’: list(range(NUMBER_OF_DISKS, 0, -1)),
‘B’: [ ],
‘C’: [ ]
}

print(rods)

source = ‘A’
auxiliary = ‘B’
target = ‘C’

for i in range(number_of_moves):
remainder = (i + 1) % 3
forward = False


if remainder == 1:
    print(f'Move {i+1} allowed between {source} and {target}')
    if not rods[target]:
        forward = True
    elif rods[source] and rods[source][-1] < rods[target][-1]:
        forward = True

elif remainder == 2:
    print(f'Move {i+1} allowed between {source} and {auxiliary}')
    if not rods[auxiliary]:
        forward = True
    elif rods[source] and rods[source][-1] < rods[auxiliary][-1]:
        forward = True

elif remainder == 0:
    print(f'Move {i+1} allowed between {auxiliary} and {target}')
    if not rods[target]:
        forward = True
    elif rods[auxiliary] and rods[auxiliary][-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())
