I don't understand why the long_total function

I understand long_total is a bad example. But if it is to calculate the total price of a list of books, why not use a for loop? The long_total example does not seem to make sense to me. Or I just totally missed the idea of something.

I actually had the same comment. In fact, why not just go with:

print(sum(b.price for b in BOOKS))

This seems to do the same calculation in a much cleaner way. Can anyone explain the advantage of using the reduce method in that example? Thanks
