Python Web抓取跨度标记，带BeautifulSoup4，价格为英镑

第一个帖子，所以请温柔一点。我正在尝试使用Python进行web刮取

我的目标是制作一个可以访问以下页面的脚本：

WWWzaraDOTcom/uk/en/sale/woman/dresses/view-all-c731533.html

我希望脚本返回a.name.item，即数据ecirp中的数据，其中span类分别是sale和crossOut对角线

我想在其他网站上使用这个脚本的时间

我下面的代码可以访问Zara、拉页面和在RE/BS中操作——但在谷歌搜索了很多BeautifulSoup和span标签之后，我无法拉任何价格

正则表达式有点伤了我的大脑，我无法从我的书中得到任何简单的代码示例来使用IRL

教美女群正确穿越的答案是什么 或者使用RE从集合字符串推断值？ 或者我应该采取另一种更好的方法。我想在商品最终上市时提醒大家

import requests
import re

r =      requests.get(“http://www.zara.com/uk/en/sale/woman/dresses/view-all-c731533.html”)
r.raise_for_status() 
html = r.text
soup = BeautifulSoup(html, 'html.parser')

---

您需要的所有数据都在产品信息标签中，url也不同，因为您必须首先选择一个地区：

import requests

from bs4 import BeautifulSoup
r =   requests.get("http://www.zara.com/ie/en/sale/woman/dresses/view-all-c731533.html?#utm_referrer=http%3A%2F%2Fwww.zara.com%2F%3Fgo%3Dhttp%253A%2F%2Fwww.zara.com%2Fshare%2Fsale%2Fwoman%2Fdresses%2Fview-all-c731533.html")
r.raise_for_status()
html = r.text
soup = BeautifulSoup(html)
prods = soup.find_all("div", {"class": "product-info"})
print(prods)
for p in prods:
    print(p.a.text)
    print("Old price  {}".format(p.find("span", {"class": "crossOut"})["data-ecirp"]))
    print("New price {}".format(p.find("span", {"class": "sale"})["data-ecirp"]))

输出：

将数据存储在dict中可能是个好主意：

from collections import defaultdict
d = defaultdict(defaultdict)
for p in prods:
    k = p.a.text
    v1 = p.find("span", {"class": "crossOut"})["data-ecirp"]
    v2 = p.find("span", {"class": "sale"})["data-ecirp"]
    d[k]["new_price"] = v1
    d[k]["old_price"] = v2
    d[k]["saving"] = float(v1.split()[0]) - float(v2.split()[0])

print(d)

这将给你：

这会给你一个类似的df：

并将数据保存到名为data.csv的csv中

要以最大的节省量加载数据和订单，请执行以下操作：

df = pd.read_csv("data.csv")


print(df.sort_values(["saving"],ascending=0))

这将产生：

                                  name    old    new  saving

14                        STUDIO DRESS  79.95  49.99   29.96
......................................................

要添加一列，该列应显示保存百分比：

df["precent_saving"] = (df["old"] - df["new"]) / df["old"] * 100
print(df)
