How to solve the error??

Question

a = int(input())
x = 0
y = ""
for i in range(a):
b = input()
y = y+b
for j in y:
if j%2==0:
x = x+j
print(x)
Here is the question:
You want to take a list of numbers and find the sum of all of the even numbers in the list. Ignore any odd numbers.

Task:
Find the sum of all even integers in a list of numbers.

Input Format:
The first input denotes the length of the list (N). The next N lines contain the list elements as integers.

Output Format:
An integer that represents the sum of only the even numbers in the list.

Sample Input:

Answer 1

Shaik.Shahir

it's simple

a = int(input())

x = 0

for i in range(1, a + 1):
b = int(input())

if (b % 2 == 0):
x = x + b

print (x)

Answer 2

If you just want to add all the even numbers in a list, e.g. my_list, you could do
print(sum(n for n in my_list if not n % 2)) 🙂

not n % 2 is the same as n % 2 == 0

Answer 3

Shaik.Shahir Here's a possibility:

print(sum(filter(lambda x: not x & 1, [int(input()) for i in range(int(input()))])))
