Question

我编写了一个python脚本，从给定网页上的所有链接中提取href值：

from BeautifulSoup import BeautifulSoup
import urllib2
import re

html_page = urllib2.urlopen("http://kteq.in/services")
soup = BeautifulSoup(html_page)
for link in soup.findAll('a'):
    print link.get('href')

运行上面的代码时，我得到以下输出，其中包括外部和内部链接：

我想删除具有完整网址（如https://www.facebook.com/KTeqSolutions/）的外部链接，同时保留诸如solutions#internet-of-things之类的链接。如何有效地做到这一点？

Answer 1

如果我对您的理解正确，则可以尝试以下方法：

l = []
for link in soup.findAll('a'):
    print link.get('href')
    l.append(link.get('href'))
l = [x for x in l if "www" not in x] #or 'https'

Answer 2

您可以从parse_url模块使用requests。

import requests

url = 'https://www.facebook.com/KTeqSolutions/'

requests.urllib3.util.parse_url(url)

给你

Url(scheme='https', auth=None, host='www.facebook.com', port=None, path='/KTeqSolutions/', query=None, fragment=None)

删除基本URL
