Pause the coroutine inside a loop

Question

Is it possible to wait for x seconds between every item in the for loop?

Like:

 for(int i = 0; i < 4; i ++) {
 
 Debug.Log(i.ToString());
 
 yield return new WaitForSeconds(1);
 
 }

This would works like so: do the code of the for one time, pause the corotine until WaitForSeconds is complete.

When I did this it's just printing 0, 1, 2, 3 every frame. I want it to print:

0...(wait 1 second)...1...(wait 1 more second)...2... and so on...

Any help would be appreciated!

Thanks from now!

The above code must have been called via a 'StartCoroutine' function, otherwise it won't be used by the MonoBehaviour's coroutine scheduler, and will all run at once!

Hence:

 IEnumerator PrintNumbers(int countUpTo, float waitTime)
 {
     for(int i = 0; i < countUpTo; i ++) {
         Debug.Log(i.ToString());
         yield return new WaitForSeconds(waitTime);
     }
 }

 // elsewhere...

 StartCoroutine(PrintNumbers(4, 1)); // Prints your numbers, waits!
