I'm an absolute beginner, but let's see if I can help. Assuming you want
to check a port on another machine,

import socket
port=25			# Port we want to test
host=machine.to.test	# Either IP address or FQDN
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
try:
	s.connect((host, port))	
	print "We made the connection"
except socket.error:
	print "Sorry, that port is not open"
s.close

Does that help?
