Not receiving serial data from arduino

[dinoel_cool]

Hi guys. So, I am trying to receive serial data from my Arduino Uno.
The Arduino sends the heading from a magnetometer over serial, but the Python code does not receive it.
This is my Python code:

import serial

Arduino = serial.Serial("COM3", baudrate = 9600) # serial device
angle = 0
Compass() #This function draws the compass 

while (True):
    
    try:
        flushInput()
        angle = Arduino.readline()
        angle = angle.strip()
        angle = int(angle)
        compasspointer.settiltangle(-angle+90)  #update heading
        print(angle)
    except:
        pass

My Arduino code:

void setup()
{
Serial.begin(9600);
}

int heading=105;//just a value
void loop()
{
Serial.println(heading);

thanks for your help!
