I am on exercise 3, I have followed the hints very closely, but the code just refuses to produce understandable answers. What should I do?

Perhaps you have forgotten to run previous cells on the notebook! Try Kernel → Restart and then start running the cells from the beginning.

it’s not such a big issue, just run all the cells from the start, it may solve the problem
