The assignment is to only write the prompt. At that point there is no need to import anything.
Once your prompt has passed the tests you can submit, but further down in the notebook there is a cell that imports get_llm_response from helper_functions followed by a cell that prints the result of passing your prompt to get_llm_response.
So if you import helper_functions yourself, the grader may object.
thanks reply, I submitted. But wording really weird "asks the LLM to generate" should fix it to avoid confuse. Suppose we should not spent time to debug those wording and system error
