我是python和所有事物的新手，并且我希望解析div类中的所有href。我的目标是创建一个程序来打开div类中的所有链接，以便能够保存与href相关联的照片。
链接：https：//www.opi.com/shop-products/nail-polish-powders/nail-lacquer
我要解析的部分是“ div-id：all_nail_lacquer”
到目前为止，我已经能够获取所有href，而这是到目前为止的结果：
import urllib
import urllib.request
from bs4 import BeautifulSoup
theurl = "https://www.opi.com/shop-products/nail-polish-powders/nail-lacquer"
thepage = urllib.request.urlopen(theurl)
soup = BeautifulSoup(thepage, "html.parser")
print(soup.title.text)
nail_lacquer = (soup.find('div', {"id":"all_nail_lacquer"}))
"""
for nail_lacquer in soup.find_all('div'):
print(nail_lacquer.findAll('a')
"""
for a in soup.findAll('div', {"id":"all_nail_lacquer"}):
for b in a.findAll('a'):
print(b.get('href'))
要打印图像链接（甚至是高分辨率图像）和标题，可以使用以下脚本：
import urllib
import urllib.request
from bs4 import BeautifulSoup
theurl = "https://www.opi.com/shop-products/nail-polish-powders/nail-lacquer"
thepage = urllib.request.urlopen(theurl)
soup = BeautifulSoup(thepage, "html.parser")
for img in soup.select('#all_nail_lacquer [typeof="foaf:Image"][data-src]'):
print(img['data-src'])
print(img['data-src'].replace('shelf_image', 'photos')) # <-- this is URL to hi-res image
print(img['title'])
print('-' * 80)

编辑：要将图像保存到磁盘，您可以使用此脚本：
import requests
from bs4 import BeautifulSoup
theurl = "https://www.opi.com/shop-products/nail-polish-powders/nail-lacquer"
thepage = requests.get(theurl)
soup = BeautifulSoup(thepage.content, "html.parser")
i = 1
for img in soup.select('#all_nail_lacquer [typeof="foaf:Image"][data-src]'):
u = img['data-src'].replace('shelf_image', 'photos')
with open('img_{:04d}.jpg'.format(i), 'wb') as f_out:
print('Saving {}'.format(u))
f_out.write(requests.get(u).content)
i += 1
