[Tutor] Help with error handling in a while loop

I'm trying to build a simple port scanner (just to learn sockets).
here is the code (doesn't work) :
host=raw_input("Enter name of host to scan: ")
start_port=input("Enter the start port: ")
end_port=input("Enter the end port: ")
print "port",start_port,"is open on",host
print "Port",start_port,"is closed on",host
As you can see, when there is an exception the socket closes (I run
the program from idle, so I don't need to exit it).
An exception will be every time the connection fails (because the port
is closed ).
I want it to print the text and go back and continue the loop whenever
there is an exception, how do I do that ?
Thanks in advance.
