在单列中对不同范围的值求和

def sum_values_in_range(values):
    sum_range1 = 0
    sum_range2 = 0
    sum_range3 = 0

    for value in values:
        if value <= 10:
            sum_range1 += value
        elif value <= 20:
            sum_range2 += value
        else:
            sum_range3 += value

    return sum_range1, sum_range2, sum_range3

# 示例数据
values = [5, 15, 25, 8, 12, 18, 30]

# 调用函数求和
sum_range1, sum_range2, sum_range3 = sum_values_in_range(values)

# 打印结果
print("范围1的求和结果：", sum_range1)
print("范围2的求和结果：", sum_range2)
print("范围3的求和结果：", sum_range3)
