Hello, I am unsure of the precedence of the '%' operator when used as the string formatting operator. I rely on the precedence chart/table in section 5.15 on page http://docs.python.org/reference/expressions.html . I must assume that the precedence of '%', described as "remainder" in the Description column also holds for that operator's use for string formatting. It would be a great help if "string formatting" were added to the description column to make this use of the '%' operator clear and explicit. Thanks, Bob Holmberg
