这是我为从 snapdeal.com 页面查找所有产品名称而编写的代码

代码：

import urllib.request
   from bs4 import BeautifulSoup as BS

   url = 'https://www.snapdeal.com/products/electronics-headphones sort=plrty'

   response = urllib.request.urlopen(url).read()
   soup = BS(response, 'html.parser')
   product_name={}
   i=0
   for title in soup.find_all('p', class_="product-title"):
           product_name[i]=title.string
           i += 1
   for i in range(1,21):
       print(product_name[i])

输出：

right_url = 'https://www.snapdeal.com/products/electronics-headphones?sort=plrty 
you_url   = 'https://www.snapdeal.com/products/electronics-headphones sort=plrty'

你错过了?url，如果你想用索引迭代，你可以使用enumerate()

soup = BS(response, 'html.parser')
product_name = [title.string for title in soup.find_all('p',class_="product-title")]
for index, value in enumerate(product_name):
    print(index, value)
