How to get back to the for loop after exception handling

I am ready to run this code but before I want to fix the exception handling:

for l in bios:
    OpenThisLink = url + l
    try:
        response = urllib2.urlopen(OpenThisLink)
    except urllib2.HTTPError:
        pass
    bio = response.read()
    item = re.search('(JD)(.*?)(\d+)', bio)
    ....

As suggested here, I added the try...except but now if a page doesn't open I get this error:

bio = response.read()
NameError: name 'response' is not defined

So the program continues to execute. Instead I want it to go back to the for loop and try the next url. I tried break instead of pass but that ends the program. Any suggestions?
