Python Coding Challenge - Question with Answer (01011125)

 

 Step-by-step explanation:

1. arr = [5, 10, 15]
   → A list (array) with three elements.

2. range(0, len(arr), 2)
   → This generates a sequence of numbers starting from 0 up to len(arr)-1 (which is 2),
   → but it skips every 2nd number.
   
   So the output of range(0, len(arr), 2) is:
   👉 [0, 2]

3. Loop runs like this:

   • When i = 0 → arr[i] = arr[0] = 5

   • When i = 2 → arr[i] = arr[2] = 15

4. print(arr[i], end=' ')
   → Prints the selected elements on the same line (because of end=' ').

✅ Output:

5 15

👉 The code prints elements at even indices (0 and 2) from the list.
