Could you please provide code example, which allows other to replicate your problem?

Executing Python 3.13.0 (tags/v3.13.0:60403a5 gives that error. Don't do that. The whole line is printed when one opens either interactive Python (REPL) or IDLE Shell. Patrick, this is likely your error, perhaps from pasting this line + real code copied from either. If you think otherwise, please say exactly what you did, including what shell/editor/IDE you are using.

Confirming that the real code starts with bad code. You should only use:

import serial
import time
import xpc 

arduino_port = 'COM3'  # Change this to the correct port for your system
baud_rate = 9600
ser = serial.Serial(arduino_port, baud_rate)

host = "127.0.0.1"  # Localhost (X-Plane running on the same machine)
port = 49009  # Default X-Plane Connect port
xp = xpc.XPlaneConnect(host=host, port=port)

try:
    while True:
        if ser.in_waiting > 0:
            button_state = int(ser.readline().strip())
            print("Button state: ", button_state)
            xp.sendDREF("sim/flightmodel/controls/gear_handle", button_state)  # Example: control gear
            time.sleep(0.1)
except KeyboardInterrupt:
    print("Exiting program.")
finally:
    ser.close()
    xp.close()
