python中使用mysql.connector连接mysql时，几乎一样的语句insert可以，但是select就报错，求助

Question

mysql的数据表是这样的： +----+------+------+ | id | name | age | +----+------+------+ | 1 | cxx | 25 | +----+------+------+ 我的python代码： cursor = conn.cursor() add_user = """insert into person(name,age) VALUES (%s,%s)""" data_user = (newName,newAge) cursor.execute(add_user,data_user) conn.commit() cursor.close() cursor = conn.cursor() select_user = """select * from person where name = (%s)""" select_data = (newName) cursor.execute(select_user,select_data) conn.commit() values = cursor.fetchall() values 上半部分的插入语句是可以正常执行的，但是下半部分的搜索语句总是报错， ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s)' at line 1 应该是字符串处理问题。。select_data没有替换掉select_user中的%s，但是上面的为什么就可以。。求高手解答

Answer 1

最终解决方案：
select_user = r'select * from person where name = %s'
select_data = (newName, )

Answer 2

"""select * from person where name = (%s)""" 

估计是这里错了，为何要加括号呢？换成下面的试试

"""select * from person where name = %s """
