Question

我的代码下面给出了一个url列表。如果我想要任何特定的url如何解决这个问题：我的代码如下：

import bs4, requests
index_pages = ('https://www.tripadvisor.in/Hotels-g60763-oa{}-New_York_City_New_York-Hotels.html#ACCOM_OVERVIEW'.format(i) for i in range(0, 180, 30))
urls = []
with requests.session() as s:
    for index in index_pages:
        r = s.get(index)
        soup = bs4.BeautifulSoup(r.text, 'lxml')
        url_list = [i.get('href') for i in soup.select('.property_title')]
        urls.append(url_list)
        print(url_list)

现在我得到的输出是Urls.Output列表，如下所示：

New_York_City_New_York.html', '/Hotel_Review-g60763-d93543-Reviews-Shelburne_NYC_an_Affinia_hotel-New_York_City_New_York.html', '/Hotel_Review-g60763-d1485603-Reviews-Comfort_Inn_Times_Square_West-New_York_City_New_York.html', '/Hotel_Review-g60763-d93340-Reviews-Hotel_Elysee_by_Library_Hotel_Collection-New_York_City_New_York.html', '/Hotel_Review-g60763-d1641016-Reviews-The_Chatwal_A_Luxury_Collection_Hotel_New_York-New_York_City_New_York.html', '/Hotel_Review-g60763-d93585-Reviews-Lowell_Hotel-New_York_City_New_York.html']

现在，如果我正在寻找上面列表中的任何特定网址，该怎么做？示例：对于Hilton_Times_Square，如何从上面的列表中找到网址？

Answer 1

寻找确切的网址：

def findExactUrl(urlList, searched):
    for url in urllist:
       if url == searched:
           reurn url

在空闲时你可以打电话

>>findExactUrl(url_list, "http://maritonhotel.com/123")
## if such url is in your list
>>"mariton Hotel" 
## or if such url is not there, nothing should show, just:
>>

另外，从您的.py文件中调用：

myUrl = findExactUrl(url_list, "http://maritonhotel.com/123")
print(myUrl)
>>"http://maritonhotel.com/123"

您可以编辑功能以返回True或i以找到它的索引。

进行更模糊的搜索

def findOccurence(urlList, searched):
    foundUrls = []
    for url in urllist:
       if url.contains(searched):
           foundUrls.append(url)
    return foundUrls

如果你想从字符串中删除一些子字符串，只需调用.replace（）方法。

for i in range(len(url_list)):
    if "[" in url_list[i]:
        url_list[i] = url_list[i].replace("[", "")

如果您有什么不明白的地方，请告诉我。另外，请认真考虑为初学者购买一些python书，或者做一些在线课程。

Answer 2

这就是我要做的事情：

keyword = "Hilton_Times_Square"
target_urls = [ e for e in url_list if keyword in e ]

无法从输出网址列表中找到网址
