如何从 python 中的 1 个字符串中删除特定案例元素

Question

here i have a string with a website html data it's stored in urldata

urldata = BeautifulSoup(urlopen(urllib.request.Request(url, headers=headers), timeout=3).read(),features="html.parser")```

when i print urldata it's showing the html data from the specific page so here i need to remove the https and http links

so i can fillter the http or https links by this way

web_page = str(urldata)
urls = re.findall('http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA- F]))+', web_page)
print(urls)

so here i'm thinking to remove the http&https links from "urldata"

I have the url list already in that url variable (type "list")

so is there any way to compare the list "urls" with "web_page" string

and remove the urls from web_page string

Answer 1

You can use re.sub() to substitute each url with an empty string:

web_page = str(urldata)
web_page = re.sub('http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA- F]))+', '', web_page)
print(web_page)

UPDATE:

web_page = str(urldata)
for url in urls:
    web_page = web_page.replace(url, '')
print(web_page)
