第1个info.stdout结果使用pprint filter进行格式化

第2个是对info的执行状态使用changed filter进行判断第3个是对one的值进行int转变，然后对str的值进行capitalize格式化第4个是对ansible变量进行判断，如果该变量定义了就引用它的值，如果没有定义就使用default内值第5个是对list内的值进行最大值max和最小值取值第6个是对list内的值使用random filter随机挑选一个，然后随机生成1000以内的数字，step是10第7个是对list内的值使用join filter连接在一起.第8个是对str值使用replace与regex_replace替换
