python mysql连接器查询字符串语法

我是python mysql connector的新手，我正在尝试获取一个查询的结果，该查询将查找p_id=0的用户_id，并将转到产品表查找该城市有多少产品可用

import mysql.connector
con = mysql.connector.connect(user='user', password = 'pass', host = 'blah.com')

cursor1 = con.cursor(buffered = True)

query = ("SELECT l.user_id, count(u.prod_id)"
        "FROM db1.users as l INNER JOIN db2.product as u "
        "ON l.u_city = u.p_city"
        "WHERE l.p_id =0 GROUP BY l.user_id limit 10;" )
cursor1.execute(query)

查询是在mysql中执行的，但是从pythonmysql连接器中我得到了以下错误

C:\Python27\python.exe C:/Python27/Lib/site-packages/mysql/connector/update_campus_user_profile_suset.py

最好使用（'stmt''）将您的查询初始化为变量并执行
不需要使用

看起来您只是在每行末尾缺少了一些空格。尝试：

query = ("SELECT l.user_id, count(u.prod_id) "
        "FROM db1.users as l INNER JOIN db2.product as u "
        "ON l.u_city = u.p_city "
        "WHERE l.p_id = 0 GROUP BY l.user_id limit 10;" )

有时使用多行字符串更为自然：

query = ("""
        SELECT l.user_id, count(u.prod_id)
        FROM db1.users as l INNER JOIN db2.product as u
        ON l.u_city = u.p_city
        WHERE l.p_id = 0 GROUP BY l.user_id limit 10
        """)

谢谢，但我想把它分成多行。：）
query = ("""
        SELECT l.user_id, count(u.prod_id)
        FROM db1.users as l INNER JOIN db2.product as u
        ON l.u_city = u.p_city
        WHERE l.p_id = 0 GROUP BY l.user_id limit 10
        """)
