## code

business_cityg = "Gardena"
business_stateg = "CA"

""", (''gas-stations'', business_nameg, business_address1g, business_cityg, business_stateg, business_zipcodeg, phone_number1g, website1g, website2g))


cursor.close()
conn.close()

我一直有这个错误

  File "testdb.py", line 51
    """, (''gas-stations'', business_nameg, business_address1g, business_cityg, business_stateg, business_zipcodeg, phone_number1g, website1g, website2g))
              ^
SyntaxError: invalid syntax

知道为什么吗？

谢谢你的帮助

更新2，我删除了“categories”上的双引号，但现在甚至

import MySQLdb  

conn =  MySQLdb.connect(host="localhost",port=22008,user="cholestoff",passwd="whoami",db="mydatabase")  
cursor = conn.cursor()  

## Find mysql version  
cursor.execute ("SELECT VERSION()")  
row = cursor.fetchone()  
print "server version:", row[0]  

website1g = "http://www.triman.com"  
business_nameg = "Triman Sales Inc"  
business_address1g = "510 E Airline Way"  
business_cityg = "Gardena"  
business_stateg = "CA"  
business_zipcodeg = "90248"  
phone_number1g = "(310) 323-5410"  
phone_number2g = ""  

cursor.execute ("""
    INSERT INTO yellowpages(categories_name, business_name)
    VALUES ('%s','%s')
""", ('gas-stations', business_nameg))              

cursor.close()  
conn.close()  

还是犯了这个错误
