Python Coding Challenge - Question with Answer (ID -211225)

 

Explanation:

1. Creating the List

nums = [[1, 2], [3, 4], [5, 6]]

We make a list named nums

It has three small lists inside it:

[1, 2]

[3, 4]

[5, 6]

2. Making the Function

def even_sum(x):

    return sum(x) % 2 == 0

We create a function named even_sum

It receives one list x

sum(x) adds the elements

% 2 == 0 checks if the total is even

True → keep it

False → remove it

3. Using filter()

res = list(filter(even_sum, nums))

filter() applies even_sum on each small list in nums

Only lists with even sum will stay

Result is converted to a list and stored in res

4. Checking Each List

[1,2] → 1+2 = 3 (odd) 

[3,4] → 3+4 = 7 (odd) 

[5,6] → 5+6 = 11 (odd) 

➡ No list has an even sum

5. Printing the Result

print(res)

It prints res

6. Final Output
