Tell us what’s happening:

Describe your issue in detail here.

Hello I have tried multiple things to solve the code but I didn’t find the right one, can anyone help me?

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}')
        elif remainder == 0:
            print(f'Move {i + 1} allowed between {range(rod(1))} and {range(rod(2))})

# User Editable Region


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

I haven’t completed this project yet but I know where the issue is in your code:

{range(rod(1))} and {range(rod(2))}

You should be inserting variables (from your function parameters) in here.
Your previous two strings used {source} and {target} and {source} and {auxiliary} respectively, so your final string should use…?

Also your string is missing a closing quote mark.

Thank you so much! I found the solution.
