# Learn Recursion by Solving the Tower of Hanoi Puzzle - Step 17

### Tell us what’s happening:

Not understanding why the code wont be accepted I have the IF statement and the f string correctly?

``````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}')

# User Editable Region

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

You don’t need to create a new variable to create this `if` statement.

Again, although the syntax and logic is correct, the instructions don’t ask you to create a new variable.

This is incorrect I did indeed have to make a variable with Remainder however the problem was with the If statement I did not include the line specified in the instruction after the “triggered when” portion.

Not sure what you mean, but I’m glad you got it

``````variable = 1 + 1
if variable == 2:
``````

Is equivalent to:

``````if 1 + 1 == 2:
``````
