python - 我怎样才能刮下li下的价格

Question

这是我的代码：

import pandas as pd
import numpy as np
from urllib.request import urlopen as ureq
from bs4 import BeautifulSoup as soup
my_url = 'https://www.newegg.com/Gaming-Video-Cards/PromotionStore/ID-1197? 
cm_sp=Cat_Video-Cards_1-_-TopNav-_-Gaming-Video-Cards'
my_url

gamestore = ureq(my_url)
page_html = gamestore.read()
gamestore.close()

page_soup = soup(page_html, "html.parser")
containers = page_soup.findAll("div",{"class":"item-container"})

问题来自以下两行：

pricetag = container.findAll("li",{"class":"price-current"})
pricetag

结果是： 我想要的只是得到价格，即

</span>$<strong>599</strong><sup>.99</sup>

我该怎么做？

Answer 1

要获得价格，您可以使用css 选择器div.item-container li.price-current strong来获取强元素并使用findNextSibling来获取sup元素。

containers = page_soup.select("div.item-container li.price-current strong")

for c in containers:
    print(c.text +  c.findNextSibling('sup').text)

这将导致：

599.99
369.99
