插入数据库时​​Python嵌套循环错误

Question

我这里有一个代码，可以从特定网站https://vancouver.craigslist.org/search/ela抓取数据。 。我的问题是当我执行代码时，它给我一个错误 'list' object has no attribute 'get_attribute'在线asdf = images.get_attribute("src") 。我正在使用 selenium 库来抓取数据。我想要的是从名为 images 的表中插入图像 url但是我不能。我的代码有什么问题吗？我对 python 还不熟悉，这就是我问问题的原因。非常感谢您的考虑。

当前代码

   x = driver.find_elements_by_class_name('hdrlnk')
    y = driver.find_elements_by_xpath('//p[@class="result-info"]/span[@class="result-meta"]//span[@class="result-price"]')
    images = driver.find_elements_by_xpath('//*[@id="sortable-results"]/ul/li/a/img')
    for img in images:
      print(img.get_attribute('src'))
      for i in range(len(x)):
        asdf = images.get_attribute("src")
        prod = (x[i].text)
        price = (y[i].text)
        image = asdf
        sql =  """INSERT INTO products (name,price,image) VALUES (%s,%s,%s)"""
        mycursor.execute(sql,(prod,price,image))
        mydb.commit()

当我评论这一行时

for img in images:
      print(img.get_attribute('src'))

并删除 asdf和 image变量，我可以插入数据，并且当我注释这行代码并保留图像的打印时，

   #for i in range(len(x)):
        #asdf = images.get_attribute("src")
        #prod = (x[i].text)
        #price = (y[i].text)
        #image = asdf
        #sql =  """INSERT INTO products (name,price,image) VALUES (%s,%s,%s)"""
        #mycursor.execute(sql,(prod,price,image))
        #mydb.commit()

我得到了我想要的结果，就像这样

x的示例数据和 y变量 i循环:

x = Spigen Magnetic Car Phone Mount
y= $20

为了将包含产品名称和图像的图像网址插入一行中，我需要做什么？ TIA。

编辑。我尝试了@terahertz的答案并像这样重写了我的代码

  x = driver.find_elements_by_class_name('hdrlnk')
    y = driver.find_elements_by_xpath('//p[@class="result-info"]/span[@class="result-meta"]//span[@class="result-price"]')
    images = driver.find_elements_by_xpath('//*[@id="sortable-results"]/ul/li/a/img')
    for img in images:
      # print(img.get_attribute('src'))
      for i in range(len(x)):
        asdf = img.get_attribute("src")
        prod = (x[i].text)
        price = (y[i].text)
        image = asdf
        sql =  """INSERT INTO products (name,price,image) VALUES (%s,%s,%s)"""
        mycursor.execute(sql,(prod,price,image))
        mydb.commit()

现在我可以插入到我的数据库中，但问题是 image列与其他列具有相同的值。就像只插入了一个图像网址。当我访问该链接时，产品名称和图像不匹配。

Answer 1

将 asdf = images.get_attribute("src") 更改为 asdf = img.get_attribute("src")

您的外循环正在使用变量 img 访问 images 列表中的每个项目。但在您的内部循环中，您正在访问 images 列表。
