Python: Continue looping after exception

Question

I have the following script (below). which will return the status code of URLs. It loops through a file and tries to connect to each host. Only problem is that it obviously stop

You need to handle exception raised by urllib.urlopen(line), something like this.

try:
    f = file(hostsFile)
    while True:
        line = f.readline().strip()
        epoch = time.time()
        epoch = str(epoch)
        if len(line) == 0:
            break
        try:
           conn = urllib.urlopen(line)
        except IOError:
           print "Exception occured"
           pass
except IOError:
    epoch = time.time()
    epoch = str(epoch)
    print epoch + ": Connection unsuccessful, unable to connect to server, potential routing issues\n"
    sys.exit()
else:
    f.close()
