Error in test 3 of That's Odd... Code Coach

Question

a =int(input())
n = []
counter = 0
sum = 0
while a > counter:
b = (input())
n.append(b)
counter += len(b)
for x in n:
if int(x) % 2 == 0:
sum += int(x)
print(sum)
Why does this fail the third test?

Answer 1

counter += len(b)

I am not sure what you are trying here. If you change this line to a -= 1 your code works.
And you can remove variable counter: while a > 0:

b = int(input())
So you don't need to convert x to int.

And theoretically you don't need to create the list.
while a > 0:
b = int(input())
if b % 2 == 0:
....

Happy coding!
