Hey Mohammed,

There are actually a few things going wrong here. Mostly it looks like you are not following the Very Specific instructions for this challenge.

  1. "The challenge ... does not need you to loop over a range of values ..." But you have created a for in loop. So, that needs to be deleted.
  2. "Change all you print statements to return statements" But you still have print statements. So, those need to be changed.
  3. "Do not worry about the default case ..."* But you have included an else clause. So, that needs to be deleted.

Once those are correct, there is also a typo in your if statement, you have (n & 5) instead of (n % 5).

So, the code is 'technically' correct (less the typo), but it need to exactly match what the instructions ask for, otherwise the code checker cannot check it. So, once you fix it all up, the challenge will pass.

Keep coding! :) :dizzy:
