Question

我想从网址中提取网站名称。对于例如https://plus.google.com/in/test.html 应该输出 - “加上谷歌”

输出： - OH MADISON STORES ADVANCEAUTOPARTS

WWW.LQ.COM/LQ/PROPERTIES/PROPERTYPROFILE.DO?PROPID=6054

string = str(input("Enter the url "))
new_list = list(string)
count=0
flag=0

if 'w' in new_list:
    index1 = new_list.index('w')
    new_list.pop(index1)
    count += 1
if 'w' in new_list:
    index2 = new_list.index('w')
    if index2 != -1 and index2 == index1:
        new_list.pop(index2)
        count += 1
if 'w' in new_list:
    index3= new_list.index('w')
    if index3!= -1 and index3== index2 and new_list[index3+1]=='.':
        new_list.pop(index3)
        count+=1      
        flag = 1
if flag == 0:
    start = string.find('/')
    start += 2
    end = string.rfind('.')

    new_string=string[start:end]
    print(new_string)
elif flag == 1:
    start = string.find('.')
    start = start + 1
    end = string.rfind('.')

    new_string=string[start:end]
    print(new_string)

以上适用于某些测试用例，但不是全部。请帮帮我。

这是你可以建立的东西;使用urllib.parse.urlparse：

from urllib.parse import urlparse

tests = ('https://plus.google.com/in/test.html',
         ('WWW.OH.MADISON.STORES.ADVANCEAUTOPARTS.COM/'
          'AUTO_PARTS_MADISON_OH_7402.HTML'),
         'WWW.LQ.COM/LQ/PROPERTIES/PROPERTYPROFILE.DO?PROPID=6054')

def extract(url):
    # urlparse will not work without a 'scheme'
    if not url.startswith('http'):
        url = 'http://' + url
    parsed = urlparse(url).netloc
    split = parsed.split('.')[:-1] # get rid of TLD
    if split[0].lower() == 'www':
        split = split[1:]
    ret = ' '.join(split)
    return ret

for url in tests:
    print(extract(url))

该函数将URL从双斜杠剥离为单斜杠：剩下的就是'清理'

def stripURL( url, TwoSlashes, OneSlash ):
    try:
        start = url.index(TwoSlashes) + len(TwoSlashes)
        end = url.index( OneSlash, start )
        return url[start:end]
    except ValueError:
        return ""
url= raw_input("URL : ")
if "www." in url:url=url.replace("www.","")
Strip = stripURL( url, "//", "/" )
# Strips anything after the last period found
Stripped = Strip[:Strip.rfind(".")]
# get rid of the any periods used in the name 
Stripped = Stripped.replace("."," ")
print Stripped
