The code you provided is an example of using a while loop in Python to iterate through a list. Here's how it works:

marks = [95, 98, 97]  # Create a list of marks
i = 0  # Initialize the index i to 0

while i < len(marks):  # Loop until i is less than the length of the marks list
    print(marks[i])  # Print the element at index i
    i = i + 1  # Increment i by 1 after each iteration

Detailed Explanation:

1. marks = [95, 98, 97]: This creates a list called marks that contains three values: 95, 98, and 97.

2. i = 0: The variable i is initialized to 0. This variable will be used to track the position of elements in the list.

3. while i < len(marks):: The while loop condition checks if the value of i is less than the length of the marks list. If this condition is true, the loop continues. In this case, len(marks) returns 3, since the list has 3 elements.

4. print(marks[i]): This command prints the element at index i in the marks list. On the first iteration, i is 0, so the first element (95) is printed. Then, i is incremented by 1, and the loop continues.

5. i = i + 1: After each iteration, the value of i is incremented by 1, which allows the loop to move to the next element in the list. Result: When running this code, you will get the following output:

95 98 97

Each value corresponds to an element in the marks list.
