To fix the code, we need to correct the comparn operator in line 3 (use == instead of = for equality check):

Corrected Code

def sum_even_numbers(numbers):
    total = 0
    for num in numbers:
        if num % 2 == 0:  # Fixed: changed = to ==
            total += num
    return total

numbers = [1, 2, 3, 4, 5, 6]
result = sum_even_numbers(numbers)
print(result)

Explanation

The original error was using the assignment operator (=) instead of the equality operator (==) in the condition. This caused a syntax error because Python expects a comparn (not an assignment) in an if statement.

After fixing the operator, the function correctly sums all even numbers in the list:
2 + 4 +6 =12 → the output will be 12.

Output:
12
