python函数实现1到100的偶数和

可以使用以下代码实现1到100的偶数和：

def even_sum(start, end):
    """Calculate the sum of even numbers between start and end."""
    total = 0
    for i in range(start, end+1):
        if i % 2 == 0:
            total += i
    return total

sum = even_sum(1, 100)
print("The sum of even numbers between 1 and 100 is", sum)

输出结果为：

The sum of even numbers between 1 and 100 is 2550
