Python parse email address with regex

Question

I'm a beginner on regex of python

target test.php code:

<html>
  <head></head> 
  <body>
    <a href="www.google.com">[email protected]</a>
    <div>[email protected]</div>
    [email protected]
    [email protected]
  </body>
</html>

This is my code:

import requests,re

email_pattern = re.compile('([\w\-\.]+@(\w[\w\-]+\.)+[\w\-]+)')

res = requests.get("http://127.0.0.1/test.php")

a = email_pattern.findall(res.text)

print a

The result :

[(u'[email protected]', u'com.'), (u'[email protected]', u'com.'), (u'[email protected]', u'gmail.'), (u'[email protected]', u'test.')]

But I want the result like:

[[email protected], [email protected], [email protected], [email protected]]

What wrong in my pattern or code ?

Why the result is multiple list containse extra com , gmail , test ?

Thank you solve my doubts !

Because of capturing group, use '([\w\-\.]+@(?:\w[\w\-]+\.)+[\w\-]+)' — Tushar

First rule is that you do never use regexp to parse HTML, it is impossible to do it right!

Once you have a block of text that you want to validate as being and email address, you google and find 2-5 very good regexps on StackOverlfow. RegExps are not python specific.

3rd, you look for a better job, trying to scrap email addresses from websites is not an easy task and everyone here hate those that are spamming us.

Make the inner group non-capturing:

([\w\-\.]+@(?:\w[\w\-]+\.)+[\w\-]+)
