Question

我正在尝试使以下Python MYSQL更新语句正确（使用变量）：

try:
    connection = mysql.connector.connect\
       (host = "localhost", user = "root", passwd ="", db = "crawling")
except:
    print("Keine Verbindung zum Server")
    sys.exit(0)



cursor = connection.cursor()

cursor.execute("TRUNCATE meta;")
connection.commit()

cursor.execute("ALTER TABLE meta AUTO_INCREMENT =1;")
connection.commit()

for j in range(1, int(outerElements)):

    for i in range(1, int(innerElements)):

        partner_ID = 6

        location_ID = 20

        headline = driver.find_element_by_xpath("//div[@id='productList']/div["+str(j)+"]/div["+str(i)+"]/div/div[2]/h2/a").text

        price = driver.find_element_by_xpath("//div[@id='productList']/div["+str(j)+"]/div["+str(i)+"]/div/div[2]/div[2]/span[2]").text[:-1]

        deeplink = driver.find_element_by_xpath("//div[@id='productList']/div["+str(j)+"]/div["+str(i)+"]/div/div[2]/h2/a").get_attribute("href")





        print("Header: " + headline + " | " + "Price: " + price + " | " + "Deeplink: " + deeplink + " | " + "PartnerID: " + str(partner_ID) + " | " + "LocationID: " + str(location_ID))


        cursor.execute('''UPDATE meta SET (price_id, Header, Price, Deeplink, PartnerID, LocationID) \
          VALUES(%s, %s, %s, %s, %s, %s)''', ['None'] + [headline] + [price] + [deeplink] + [partner_ID] + [location_ID])

        connection.commit()


   cursor.close()
   connection.close()

执行代码时，我收到以下错误消息：

Traceback (most recent call last):

有人可以帮帮我吗？任何反馈都表示赞赏。

尝试更改

story        = 'A long foo ago, in a bar baz, baz away...'
search_terms = ['foo', 'bar', 'baz']
story.split(/\W+/).count { |word| search_terms.include? word }
  # => 4

的

UPDATE meta SET (price_id, Header, Price, Deeplink, PartnerID, LocationID)
