虽然我在python中得到了10个以上的结果，但现在我只能得到mysql数据库中出现的最后一个产品（id为12以及价格、图片等信息）。我需要修复它，使他们都出现，而不仅仅是一个产品。
python代码如下。

import requests

import mysql.connector

url = 'https://www.newegg.com/Video-Cards-Video-Devices/Category/ID-38?Tpk=graphics%20card'

cursor = conn.cursor()  

item_container = soup.find_all('div', class_='item-container')

def get_data():
lists = []
    for index, item_name in enumerate(item_container):
        name = item_name.find_all('a', class_='item-title')[0].text
        lists.append({'name': name})
        lists[index]['index'] = index

    for index, item_price in enumerate(item_container):

        if price == None:

            price == ('Not Available')
            lists[index]['price'] = price

        else:

            price = ('$' + price.text +'.99')
            prices = []
        lists[index]['price'] = price

    for index, item_picture in enumerate(item_container):
            picture = 'http:' + item_picture.find('img', class_='lazy-img')['data-src']

            lists[index]['picture'] = picture

    for index, item_shipping in enumerate(item_container):
            shipping = (item_shipping.find('li', class_='price-ship').text).strip()
            lists[index]['shipping'] = shipping

def create_table():

                "VALUES (%s, %s, %s, %s, %s)")

    data_item = (val_index, val_name, val_picture, val_price, val_shipping)

    cursor.execute("DELETE FROM newegg ")
    conn.commit()
    cursor.execute(add_item, data_item)  
    conn.commit()

    cursor.close() 
    conn.close()                                                                  

create_table();
get_data()
