best aproach to pass an email from the url to a view?

I put the Email that I got from a form into the url (I am using the url as a variable to store the email)

and look like this

http://127.0.0.1:8000/polls/vote/thank/a@b.com/

url:

url(r'^vote/thank/(?<your_email>   #here should be RE catching the email    )$', views.thank),

view:

def thank(request, your_email=None):
    c = {"thanks_body": "thanks_body view"}
    c["his_email"] = your_email
    return render(request, "thanks.html", c)

I am having issues to try to come up with a RE to grab the email

I try http://stackoverflow.com/questions/201323/using-a-regular-expression-to-validate-an-email-address

using it on my url

such

url(r'^vote/thank/(?<your_email>^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ ', views.thank),

 and I still don't catch it, I think because I am just copy pasting but in the url string should be arrenge diferntly?

I was reading about a  get function that can make a quary on the url like a dictionary?  any example on how to use it?

thanks,  (I order a book for RE  =)  just to be able to udertand a little bit more   )
