Plate", 0, 4, 3, 5.95 ) ] ) ~~~ Here we are inserting three rows of five values. Notice that there is a mix of types (strings, ints, floats) though we still only use %s. And also note that we only included format strings for one row. MySQLdb picks those out and duplicates them for each row. MySQLdb会自动适应类型，实际上可以不必在乎类型了？ 但是其他数据库包会么？
