...and why are those lines there instead of in the method 
get_items_from_user() (which is a misnomer anyway because the method is 
getting item prices not items, e.g. item = bread, item_price=$2.50)?

How about get_prices() and get_input() instead of get_items_from_user() 
and ask_user_for_number()?
