Python in Plone: trying to append a variable to RESPONSE.redirect

I have a python script in Plone, I'm having trouble appending a variable to RESPONSE.redirect. I get a invalid syntax error.

test = '1000'

RESPONSE.redirect(("/Plone/user_bla开发者_运维技巧st/public_blast_results/%s" % (test))

---

Its me being stupid, theres an extra bracket by redirect.
