In python, the django framework uses the regular expression to search for the email address on the page.

This article mainly introduces the method of using the django framework in python to search for the email address on the page through regular expressions. it involves the usage skills of the django framework and regular expressions, for more information, see the example in this article. Share it with you for your reference. The specific implementation method is as follows:

import refrom django.shortcuts import renderfrom pattern.web import URL, DOM, abs, find_urlsdef index(request): """ find email addresses in requested url or contact page """ error = '' emails = set() url_string = request.GET.get('url', '') EMAIL_REGEX = re.compile(r'[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}', re.IGNORECASE) # use absolute url or domain name url = URL(url_string) if url_string.startswith('http') else URL(domain=url_string,protocol='http') if url_string:  try:   dom = DOM(url.download(cached=True))  except Exception, e:   error = e  else:   contact_urls = { url.string }   # search links of contact page   for link in dom('a'):    if re.search(r'contact|about', link.source, re.IGNORECASE):     contact_urls.add(      abs(link.attributes.get('href',''), base=url.redirect or url.string))   for contact_url in contact_urls:    # download contact page    dom = DOM(URL(contact_url).download(cached=True))    # search emails in the body of the page    for line in dom('body')[0].content.split('\n'):     found = EMAIL_REGEX.search(line)     if found:      emails.add(found.group()) data = {  'url': url_string,  'emails': emails,  'error': error, } return render(request, 'index.html', data)

I hope this article will help you with Python programming.
