错误“并非在格式化字符串时转换了所有参数”

Question

这是我的代码，并且在python 2.7中出现错误“不是在格式化字符串时转换了所有参数”，我在这里不明白我在做什么错，有人可以帮忙吗？谢谢！

import csv
import pymysql


mydb = pymysql.connect(host='127.0.0.1', user='root', passwd='root', db='jupix', unix_socket="/Applications/MAMP/tmp/mysql/mysql.sock")
cursor = mydb.cursor()
csv_data = csv.reader(open('activeproperties.csv'))

print("Connect Success")

for row in csv_data:
	cursor.execute('INSERT INTO ALL_ACTIVE_PROPERTIES(Property ID, Reference_Number,Address_Name,Address_Number,Address_Street,Address_2,Address_3,Address_4,Address_Postcode,Owner_Contact_ID,Owner_Name,Owner_Number_Type_1,Owner_Contact_Number_1,Owner_Number_Type_2,Owner_Contact_Number_2,Owner_Number_Type_3,Owner_Contact_Number_3,Owner_Email_Address,Display_Property_Type,Property_Type,Property_Style,Property_Bedrooms,Property_Bathrooms,Property_Ensuites,Property_Toilets,Property_Reception_Rooms,Property_Kitchens,Floor_Area_Sq_Ft,Acres,Rent,Rent_Frequency,Furnished,Next_Available_Date,Property_Status,Office_Name,Negotiator,Date_Created)' 'VALUES(%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)', row)

mydb.commit()
