在 Python 中编写一个函数，以数字列表作为输入并返回列表中所有偶数的总和。

def sum(numbers):
    # Using a list comprehension to filter even numbers
    even numbers = [number for number in numbers if number % 2 == 0]
    
    # Calculating the sum of even numbers
    sum even numbers = sum(even numbers)
    
    return sum even numbers

Answer 1

添加一些下划线就可以了。

def sum(numbers):
    # Using a list comprehension to filter even numbers
    even_numbers = [number for number in numbers if number % 2 == 0]
    
    # Calculating the sum of even numbers
    sum_even_numbers = sum(even_numbers)
    
    return sum_even_numbers
