python">from clickhouse_driver import Client

ck = Client(
	user=clickhouse_config['user'], 
	password=clickhouse_config['password'],
    host=clickhouse_config['host'], port=clickhouse_config['port'], 
    database=clickhouse_config['database']
)

sql = "SELECT id,author,publisher,title,summary FROM bigdata.dw_dim_metadata_book_cip_all WHERE `title` = '互联网' limit 1"
res = ck.execute(sql)  # list

这里特别要注意的一点是端口问题，HTTP协议（默认端口8123）；TCP (Native)协议（默认端口号为9000），Python里的clickhouse_driver用的TCP端口9000，DBeaver使用的是HTTP端口。

如果端口错误包报错：UnexpectedPacketFromServerError: Code: 102. Unexpected packet from server 220.202.33.52:19100 (expected Hello or Exception, got Unknown packet)
