You don't normally use a while loop or a counter to iterate over a list.
Such a question should only be used as a precursor to discussing better
methods of achieving the required result.
While loop:

Better, use a for loop:
s = 0
for i in list_a:
s += i
print (s)
Even better, use sum():
s = sum(list_a)
print (s)
And if you only want to display the answer:
print (sum(list_a))
