如何将数字分配给返回的 python 数据列表，我可以调用这些数据进行打印

Question

这里完全是菜鸟。我在网上搜索过，但找不到我正在尝试做的事情的答案。我的代码在这里：

import bs4 as bs
import urllib.request

sauce = urllib.request.urlopen('https://www.amazon.com/gp/rss/
bestsellers/kitchen/289851/ref=zg_bs_289851_rsslink').read()

soup = bs.BeautifulSoup(sauce,'lxml')

for title in soup.find_all('title'):

    output = title.string

    print(output)

给我这个输出：

我想做的是将每个项目编号保存到一个列表中，我可以调用...例如打印项目 1 或项目 2 等，它只会打印特定行.

非常感谢您的帮助。

Answer 1

一个快速的解决方案可能是执行如下操作

import bs4 as bs
import urllib.request

sauce = urllib.request.urlopen('https://www.amazon.com/gp/rss/bestsellers/kitchen/289851/ref=zg_bs_289851_rsslink').read()

soup = bs.BeautifulSoup(sauce,'lxml')

output_list = list()

for title in soup.find_all('title'):

    output = title.string
    output_list.append(output)

现在每个结果都在您想要的列表中。

由于标题采用索引 0，您只需执行以下操作即可打印每个数字的结果：

print(output_list[1]) # Print the first item
print(output_list[2]) # Print the second item

要逐行获取所有内容，可以使用类似以下的方法：

for i in range(1, len(output_list)):
    print(output_list[i])

希望对您有所帮助。
