删除Python中的重复URL,包括包含正斜杠的URL,python,web-scraping,duplicates,Python,Web Scraping,Duplicates,下面的程序为我提供的输出包括带或不带正斜杠的URL(例如ask.census.gov和ask.census.gov/)。我需要消除其中一个。提前感谢您的帮助 from bs4 import BeautifulSoup as mySoup from urllib.parse import urljoin as myJoin from urllib.request import urlopen as myRequest my_url = "https://www.census.gov/progra

下面的程序为我提供的输出包括带或不带正斜杠的URL(例如ask.census.gov和ask.census.gov/)。我需要消除其中一个。提前感谢您的帮助

from bs4 import BeautifulSoup as mySoup
from urllib.parse import urljoin as myJoin
from urllib.request import urlopen as myRequest

my_url = "https://www.census.gov/programs-surveys/popest.html"

# call on packages
html_page = myRequest(my_url)
raw_html = html_page.read()
html_page.close()
page_soup = mySoup(raw_html, "html.parser")

f = open("censusTest.csv", "w")

hyperlinks = page_soup.findAll('a')

set_urls = set()

for checked in hyperlinks:
    found_link = checked.get("href")
    result_set = myJoin(my_url, found_link)
    if result_set and result_set not in set_urls:
        set_urls.add(result_set)
        f.write(str(result_set) + "\n")

f.close()
这段代码将检查字符串中的最后一个字符是否是“/”,如果是,它将删除它

python字符串操作的好例子:

您可以随时-如果存在,则会将其删除,如果不存在,则不会执行任何操作:

result_set = myJoin(my_url, found_link).rstrip("/")

执行此代码后,
我的url
是否会变得等于
/
?alecxe是对的,我已修复了我的错误。非常感谢。
result_set = myJoin(my_url, found_link).rstrip("/")
