#coding:utf-8
import pymysql

conn = pymysql.connect(
    host = 'localhost',
    port = 3306,
    user = 'root',
    passwd = 'mysql',
    db = 'cltest'
)

cur = conn.cursor()
sql = "select id,status from cost_cl where id in (1,2)"
cur.execute(sql)
rows = cur.fetchall()
for dr in rows:
    print(dr)

结果
