Good Day All, I am new to Python and I came across the concept of Composition and Aggregation the other day in Dusty Philips's Python 3: Object-Oriented Programming book.
Based on my reading, what I gathered was that Composition implies a relationship where the child cannot exist independent of the parent while Aggregation, on the other hand, implies a relationship where the child can exist independently of the parent. However, in one of the paragraph of the book, *Dusty mentioned that composition is aggregation* (refer to the snapshot below, the sentence which has been highlighted in yellow). I am really confused by this statement and I appreciate that if someone could enlighten me on this as I do not really see how aggregation can be equivalent to composition if the child in one case can exist independently while the other could not exist independently of the parent.
