IndexError: list index out of range. Trying to create a list of dictionaries for BeatifulSoup items

Question

我正在尝试创建一个字典列表，其中包含从网站上抓取的数据。数据列表：价格，每克价格，品牌。

在第一部分中，我提取价格和 price_per_gramm 并将数据附加到列表中，一切正常。现在我有一个字典列表，其中唯一的一个字段“品牌”是空的。所以我尝试用实际数据替换那些空字段并遇到 IndexError.

soup = BeautifulSoup(open("./FULL_data.html"), "html.parser")
list_of_sku = []

for divs in soup.find_all('div', attrs={"class" : "col-xs-6 col-sm-4"}):
    item = {"Brand": "",
            "price": "",
            "price per gramm": ""}
    links = divs.find_all("tr")
    for row in links:
        # We get list of prices here
        item_text = row.find('td')
        item_text2 = row.find('span', {"class": "text-primary"}).text
        if item_text and item_text2:
            item["price"] = str(item_text.text)
            item["price per gramm"] = str(item_text2)
            list_of_sku.append(item)

    #We get a brand here
    i=0
    for row in soup.find_all('div', attrs={"class" : "js-equalized-brand"}):
        list_of_sku[i]["Brand"] = str(row.text)
        print(list_of_sku[i]["Brand"])
        i += 1
    print(list_of_sku)

这是一个错误：

    Original Stash

Traceback (most recent call last):
  File "/Users/PycharmProjects/MyFirstOne/WEBSCRAPING/Work with Soup data.py", line 41, in <module>
    list_of_sku[i]["Brand"] = str(row.text)
IndexError: list index out of range

请帮忙寻找解决办法。

Answer 1

for divs in soup.find_all('div', attrs={"class" : "col-xs-6 col-sm-4"}):

之间的缩进级别不同

和

i=0
for row in soup.find_all('div', attrs={"class" : "js-equalized-brand"}):
    list_of_sku[i]["Brand"] = str(row.text)
    print(list_of_sku[i]["Brand"])
    i += 1
print(list_of_sku)

从而导致每个 divs 的第二个循环为 'play'。（也重置）。
