Hello Andy @Andy6,

This error indicates that the function isn’t implemented correctly, but it is not uncommon. While it is your work to debug your code, we can provide some hints.

  1. Cell #5. Can’t compile the student’s code. This says your cell #5 has a problem.
  2. To find out which is cell #5, go to your notebook, click “Kernel” > “Restart & Run All”
  3. All code cells are then queued to run. As a cell finishes, a number will show up on the left like In [1].
  4. Wait until you see In [5], then that’s the cell #5. I expect you to see more an error traceback beneath the cell #5.
  5. You may or may not see this error message “IndentationError: unexpected indent”, but regardless of what message you see, google it to understand more.
  6. If you want to know how to indent correctly, you may check out this post.

Good luck!
