Python中的函数总和

def calculate_sum(numbers):
    """计算并返回数字列表的总和"""
    total = 0
    for number in numbers:
        total += number
    return total

# 使用示例
numbers_list = [1, 2, 3, 4, 5]
result = calculate_sum(numbers_list)
print("总和是:", result)

numbers_list = [1, 2, 3, 4, 5]
result = sum(numbers_list)
print("总和是:", result)

def calculate_sum(numbers: list) -> int:
    """计算并返回数字列表的总和"""
    if not isinstance(numbers, list):
        raise TypeError("参数必须是列表类型")
    total = 0
    for number in numbers:
        if not isinstance(number, (int, float)):
            raise TypeError("列表元素必须是数字类型")
        total += number
    return total
