Python调用kylin接口实现业务

需求：

我这边要实现每天点击最多的n个用户，通过kylin界面写sql，不支持max，所以改为调用kylin接口来实现，代码如下：

#!/usr/bin/env python
# coding=utf-8

import sqlalchemy as sa

def kylin_query_show(conn_str, query_sql):
    res_dic = {}
    kylin_engine = sa.create_engine(conn_str)
    results = kylin_engine.execute(query_sql)
    for line in results:
        userid = str(line[0]).strip()
        datetime = line[1].strip()
        per_count = line[2]
        if datetime not in res_dic:
            res_dic[datetime] = []
            res_dic[datetime].append((userid, per_count))
        else:
            res_dic[datetime].append((userid, per_count))
    return res_dic

if __name__ == "__main__":
    conn_str = "kylin://username:password@ip:7070/database?version=v1"
    query_sql = "select  userid, datetime, count(*) c from xxx_report group by userid, datetime"
    res_dic = kylin_query_show(conn_str, query_sql)

    tmp_list = []
    
    for k, v in res_dic.items():
        final_userid_count_list = sorted(v, key = lambda x: x[1], reverse=True)
        final_userid_count_list = final_userid_count_list[0:5]
        tmp_list.append((k, ','.join([':'.join([u_c[0], str(u_c[1])]) for u_c in final_userid_count_list])))

    res = sorted(tmp_list, key = lambda x:x[0], reverse=True)

    for i in res:
        print "\t".join(i)
