python - print out ports with their names

I have the following code written in 2.7 python:

#...import stuff

remoteServer = raw_input("Enter a remote host to scan: ")
remoteServerIP = socket.gethostbyname(remoteServer)

print "Please wait, scanning remote Host", remoteServerIP

try:
    for port in xrange(1, 1024):
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        result = sock.connect_ex((remoteServerIP, port))
        if result == 0:
            print "port {}:    open".format(port)
        sock.close

except KeyboardInterrupt:
    print "\nexiting..."
    sys.exit()

Output:

Enter a remote host to scan: www.myexamplesite.com
Please wait, scanning remote Host xxx.xxx.xx.xx
port 21:    open
port 22:    open
...

But the problem is that I also want to know which ports are used and for what they are used just like: 

#... as usual
port 1 httpserver
port 2 chat server
...

but this is only printing the ports from 1 to 1024 is there a function/way to do this?

socket.getservbyport() will translate port numbers into the service expected to be running on that port (via /etc/services), but won't actually communicate over the port to find out what is really running.
