Nested loops

Student submission

def total_even_numbers(numbers):

result = 0

for number in numbers:

if number % 2 == 0:

result += number

return result

Correct approach

The loop correctly checks each number and adds only even values.

Make it more concise

Try combining sum() with a generator expression while keeping the intent readable.
