Pyserial again

Here is my code ; why after the readline the port close?

        ser = serial.Serial(0)
        ser.baudrate = 9600
        ser.parity = serial.PARITY_ODD
        ser.stopbits = serial.STOPBITS_TWO
        ser.bytesize =serial.EIGHTBITS
        ser.setRTS(level = 0)
        ser.setDTR(level = 0)
        ser.timeout = 1

        ser.readline()

    Why after this the port close.
