Read the fine documentation at http://pyserial.sourceforge.net/:

     Parameters for the Serial class
     
     ser = serial.Serial(
         port=None,              #number of device, numbering starts at
                                 #zero. if everything fails, the user
                                 #can specify a device string, note
                                 #that this isn't portable anymore
                                 #if no port is specified an unconfigured
                                 #an closed serial port object is created
         baudrate=9600,          #baudrate
         bytesize=EIGHTBITS,     #number of databits
         parity=PARITY_NONE,     #enable parity checking
         stopbits=STOPBITS_ONE,  #number of stopbits
         timeout=None,           #set a timeout value, None for waiting forever
         xonxoff=0,              #enable software flow control
         rtscts=0,               #enable RTS/CTS flow control
     )

You can use those as well, but they're non-portable.  
serial.Serial(port=0) will open the first serial port on either
windows or linux.
