When you press the left / right scrolling object around its axis

Question

Hello! Sorry for my English, how to make that used for example when I click the left object in the scene begins to turn left around its axis, and similarly to the right. Doing so:

 void Update () {
         if(Input.GetKey("left")) {
             print("left");
             transform.rotation = Quaternion.AngleAxis(10, Vector3.left);
         }
 }

It's not right, I do not understand these Vector3, tried so many things and nothing really happened. There is a simple way to what? I was still doing something like creating third variables xyz, and Input.GetKey ("left") wrote (just syntax is not remember, but something like this) Vector3 (x, y, z); y + = 10; Yes, when you press it's cool, but do not go where you want.

And I tried to do like this, but it seems to me that this is not the right way, because I'm using Tuch and I need that when you press all happened.

 public class Example : MonoBehaviour {
     public float speed = 0.1F;
     void Update() {
        
 if(Input.GetKey("left")) {
             print("left");
              Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
             transform.Translate(-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);
         }
     
 }
 }

Please help me, I am in despair(

You can use Quaternion.Euler(x, y, z) . where each parameter give the ability to rotate your object on its local axis.

 public float spin_speed;
 private float rotate_y ;
 
 void Update () {
 if(Input.GetKey("Left")){
 rotate_y +=(spin_speed * Time.deltaTime);
 }else if(Input.GetKey("Right")){
 rotate_y -=(spin_speed * Time.deltaTime);
 }
 rotate_y = rotate_y%360.0f;
 this.transform.rotation = Quaternion.Euler(0, rotate_y, 0);
 }

This will make your object rotating on its local y axis.
