python(used form a nominal expression)uuidmodule provisionUUIDClasses and Functionsuuid1(), uuid3(), uuid4(), uuid5() to generate1, 3, 4, 5各个版本(used form a nominal expression)UUID

uuid.uuid1([node[, clock_seq]]) : hostsID, product key (software), 和时间戳to generateUUID, 可保证全球范围(used form a nominal expression)唯一性
