Answer:
sum2 = 0
counter = 0
lst = [65, 78, 21, 33]
while counter < len(lst):
  sum2 = sum2 + lst[counter]
  counter += 1
Explanation:
The counter variable is initialized to control the while loop and access the numbers in lst
While there are numbers in the lst, Â loop through lst
Add the numbers in lst to the sum2
Increment counter by 1 after each iteration
