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

Answer 1

You could try catching the exception inside the while loop as 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)
            print epoch + ": Connection successful, status code for " + line + " is " + str(conn.code) + "\n"
        except:
            epoch = time.time()
            epoch = str(epoch)
            print epoch + ": Connection unsuccessful, unable to connect to server, potential routing issues\n"
except IOError:
    pass
else:
    f.close()
