bookList & while Loop

We've already integrated lists into for loops.

To interact with the list now, we'll require one crucial function: len(list). This function provides the list's length.

Don't fret; you'll grasp it!

Examine the code below:


              
1234567

            
numbers = [1, 2, 4, 5, 7]
i = 0

# Printing all elements from the list
while i < len(numbers):
  print(numbers[i])
  i += 1
copy

How does the code work?

Task

Calculate the sum of the squares of the numbers in the list.

  1. Initialize a while loop, using i as the index to iterate through the numbers.
  2. Accumulate the squares of the numbers into the counter to compute the sum.
  3. Display the value stored in the counter.
