Describe the bug
A clear and concise description of what what you were trying to accomplish and what went wrong. Vague statements like X does not work are not helpful. Imagine if one of your students sent you an email that said, "My program doesn't work, whats wrong with it?" Could you help them with only that to go on?

Maybe include a function that changes the array after stating that it is possible? As in replacing the array values so that it is all the average?

Traceback

Section 4.3 > paragraph that proceeds

They are not active codes, that is why, in both versions of the book, there is no active code on 4.3; instead, all of them are listings.
