For I in LL:
table_name = i[0] #表名
table_attr = i[1] #表的属性
#修改时间1528353247347, 13 bits to milliseconds, need to be converted to a timestamp of 10 bits to seconds (float type required)
table_modify_time=table_attr[' Modificationtime ']/1000.0
#使用localtime () and formatted output strftime () convert timestamps to normal format
Table_modify_time_format=time.strftime ('%y-%m-%d%h:%m:%s ', Time.localtime (table_modify_time))
Print (table_name)
Print (TABLE_ATTR)
Print (table_modify_time) #表的修改时间, sec
