如何从html中提取价格并存储到变量中？

Question

我试图从这些裤子中提取价格并将其放入变量中。我看到其他解决方案在 html 中有类似“itemprop”的内容，但我的没有。这是一个屏幕截图：这是我到目前为止的代码：import requestsimport timefrom bs4 import BeautifulSoupimport jsonurl = 'https://www.urbanoutfitters.com/search?q=cargo%20pant&sayt=true'headers = {'User-Agent':'Mozilla/5.0'}response = requests.get(url, headers = headers)response.status_codeprint (response)soup = BeautifulSoup(response.content,'html.parser')page = requests.get("https://www.patagonia.ca/shop/mens-hard-shell-jackets-vests")soup = BeautifulSoup(page.content, 'html.parser')div_price = []# Loop on elementsfor pant in soup.find_all('p', {'class':'c-pwa-product-price c-pwa-product-tile__price'}):    span_price = pant.find('span', {'aria-label': 'class'})    if span_price:        div_price.append(span_price.get('content'))print(div_price)谢谢！！！！

Answer 1

一些改进：

1. 您的soup变量已被第二页替换。

2. 您可以使用soup.find_all('span', {'class':'c-pwa-product-price__current'})直接搜索价格。

像下面这段代码：

import requests

import time

from bs4 import BeautifulSoup

import json

url = 'https://www.urbanoutfitters.com/search?q=cargo%20pant&sayt=true'

headers = {'User-Agent':'Mozilla/5.0'}

response = requests.get(url, headers = headers)

soup = BeautifulSoup(response.content,'html.parser')

# page = requests.get("https://www.patagonia.ca/shop/mens-hard-shell-jackets-vests")

# print(page.text)

# soup = BeautifulSoup(page.content, 'html.parser')

div_price = []

# Loop on elements

for pant in soup.find_all('span', {'class':'c-pwa-product-price__current'}):

    div_price.append(pant.text)

print(div_price)

结果：
