嗨,我正在尝试使用Python 2.7和Beautifulsoup查找网站上的页面数。我尝试使用此代码从分页行中获取页数。
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import urllib2
from bs4 import BeautifulSoup
headers = {'User-Agent': 'Mozilla/5.0'}
req = urllib2.Request("https://www.sikayetvar.com", None,headers)
resp = urllib2.urlopen(req)
html = resp.read()
soup = BeautifulSoup(html)
pages = soup.find_all('div', attrs = {'class' : 'pagination row'})
for page in pages:
print page.text
输出如下: 1个 2 3 4 5 6 7 ... 807
我只需要数字807,但是汤。我应该把它变成一个字符串并找到最大数,在这种情况下(...)会产生问题,我想还是应该尝试找到findall的最后一个元素,但这又不是一个Unicode列表。我真的需要一些帮助,谢谢。
答案 0 :(得分:1)
我无法安装urllib。所以我要使用requests
库。您可以使用pip install requests
import requests
from bs4 import BeautifulSoup
headers = {'User-Agent': 'Mozilla/5.0'}
response = requests.get("https://www.sikayetvar.com/a101", headers = headers)
soup = BeautifulSoup(response.text,'lxml')
#This will you all a tags in div that has pagination class
pages = soup.select('div.pagination a')
#Last element is next page. The previous is your last page number.
#So we are going to take second last item
print(pages[-2].text)
#Output is 807
