ALL functions need a formatted docstring – see the bottom of Mod 3 Lesson 1 Activity for the requirements. Module Seven Lesson Five Activity View Split on Breaks video .split() by default, splits a string at spaces (" ") to create a list tip = "Notebooks can be exported as .pdf" tip_words = tip.split() for word in tip_words: print(word) Concept: Converting a string to a list with .split() Examples

Concept: Build a string from a list Examples: .join()
