使用带有外部变量的python将数据插入mysql

Question

我有一张表格，我需要在其中填充来自txt 文件的电子邮件地址、来自python 变量的日期和来源。在代码下方，a 是来自txt 和b 的变量，c 是我需要插入的python 变量

import csv,MySQLdb,os,os.path,datetime as dt
from sys import argv
path = argv
prompt = '>'
filename = raw_input(prompt)
fname = os.path.basename(filename)
source = fname
print "",source
date = dt.datetime.today().strftime("%d/%m/%y")
date_log = date
print "",date_log
db = MySQLdb.connect("localhost","root","passwd","testdb")
x = db.cursor()
csv_data  = csv.reader(file(filename))
for row in csv_data:
    print row
    query = (" INSERT INTO test(a,b,c) VALUES (%s,%s,%s)",row)
    x.execute(query, (date_log, source))
db.commit()
db.close()

这里出现如下错误：

File "csv2mysql.py", line 31, in <module>
    x.execute(query, (date_log, source))
  File "/usr/lib/python2.7/dist-packages/MySQLdb/cursors.py",line159,in execute
    query = query % db.literal(args)
TypeError: unsupported operand type(s) for %: 'tuple' and 'tuple'

非常感谢任何帮助

替换查询字符串

 query = (" INSERT INTO test(a,b,c) VALUES %s") %(row,)

或

 query = (" INSERT INTO test(a,b,c) VALUES %s") % str(row)
