My Django/Python Code is Not Rendering HTML <a> Tag in HTML Page

I want something similar to Twitter mentions that are turned into links but it is not working. If we assume we have message = 'Do not forget to come with the Python book, @friend'

#function to convert @mentions to links
def mentions(message, username):
    this_user_handle = reverse('mysite:profile', args=[username])
    new_message = re.sub(r'(@\w+)', r"<a href= '#'>\g<0></a>", message)
    new_message.replace('#', this_user_handle)
    return new_message

mentions(message, 'yax') returns Do not forget to come with the Python book, <a href= '#'>@friend</a>'. The # is not replaced and the new_message still displays as is in HTML page:

<p class= 'Post'>
    {{ new_message|linebreaksbr}}
</p>

This displays this:

Do not forget to come with the Python book, <a href= '#'>@friend</a>'

Instead of:

Do not forget to come with the Python book, @friend

How do I get around this? Thank you in advance!

Replace returns a new string.

new_message = new_message.replace("#", "...")

Also Django automatically escapes HTML in templates, to disable it use the safe filter.

The content is being automatically escaped to prevent things like script injection. Use the |safe filter is you're certain that it can't contain anything nasty.

Use kwargs instead of args:

reverse('profile', kwargs={'user_name': username})

You should replace the href='' by href="" to avoid mixing things you don't want to mix (you would need to replace that in several places tho).
