That’s odd

Question

In the That’s odd challenge, a list of numbers is generated, and the coder has to come up with a code to find the sum of all the even numbers on that list
eg: [5, 4, 6, 1, 1, 8, 2] (input)
Output: 20
It seemed easy to me at first, but I have been struggling with it for a little while now and not making progress.
Here is my code so far:

x = int(input())
num = 0
for i in range(x):
y = int(input())
if (y%2) ==0:
num += i
print(num)

Insight as to what I am doing wrong would be appreciated.

In your example num was to be the final result as my s does here ..
When you input your y you then went to condition fine but if condition met you added i to num verses y to num
So your end result was based on loop number instead of new value given in y.

in my example pulling from an array

# array
n = [1,2,3,4,5,6,7,8,9]
# sum
s=0
# digits in array
for d in n:
# if digits divisible by 2 equals zero
if (d%2 == 0):
# if condition met add digit to sum
s += d
# result
print(s)

if you know how many inputs you plan to use and are not using an array then do something like this ..

In the following example I am saying 10 inputs needed for this problem

s=0
# digits to be input range(?)
for i in range(10):
d = int(input())
# if digits divisible by 2 equals zero
if (d%2 == 0):
# if condition met add digit to sum
s += d
# result
print(s)

Answer 3

I changed my code to:

x = []
s = 0
for i in x:
if i % 2 == 0:
s += i

print(s)

Which I thought might work, although the ouput was always 0. Since there are a few different lists in the challenge to compute, I think I have to take the generated list as input. If this is the case, how do I do so?
