800 PointsFor book in books:
When it has:
print("Books:") for book in books: print("* " + book)
Then when the script is run it bullets each book with *. This is the only reference to "book." I guess I don't understand how it distinguishes between singular and plural. Is it just the way Python is coded? ie would each item in the list be book since the overall list name is books?

Front End Web Development Techdegree Graduate 84,738 Pointsbooks is a variable that has already been declared. book is a new local variable used for each iteration through the loop. They could have been named anything. Python doesn't have any magic that's detecting the difference between singular and plural in English. It just happens that two examples here were book/books and attendee/attendees. This is a nice logical way of naming the variables, but we're in control of naming these variables anything that we want.
booksThatIOwn = ["Not", "Very", "Many"]
for b in booksThatIOwn:
print(b)
