How to access the output value coming from Arduino JSN-SR04T sensor through Python?

Question

I've been trying to get the data from my arduino to pycharm IDE. The sensor I'm using is JSN-SR04T. However, when I'm trying to get the data from arduino, there are multiple values. How can I get the first value (i.e. the distance measured by the sensor)? The second value (266) is a constant sent by the arduino.

#include <NewPing.h>

#include <MedianFilter.h>

#include <Wire.h>

#include <cvzone.h>

#include <Servo.h>

#define pinTrigger  12

#define pinEcho     11  
#define maxDistance 450 

Servo servo1;

SerialData serial(2,3);

int valueRec[2];

int valueSend[1];

NewPing sonar(pinTrigger, pinEcho, maxDistance);

MedianFilter filter(31,0);

void setup() {

  Serial.begin(9600);

  servo1.attach(9);

}

void loop() {
  delay(100);                     
  unsigned int o,uS = sonar.ping();

  filter.in(uS);
  o = filter.out();

  int sonar_data = o/US_ROUNDTRIP_CM;

  valueSend[0] = sonar_data;

  serial.Send(valueSend);

  Serial.print("Ping: ");

  Serial.print(sonar_data); 

  Serial.println("cm");
}

Python Code

Hope you can help me. Thank you in advance.
