是否可以在不使用Python的sum()、min()或max()函数的情况下简化此函数？

def calculate_stats(numbers):
    if not numbers:  # 检查列表是否为空
        return None, None, None

    total = 0
    min_value = numbers[0]
    max_value = numbers[0]

    for number in numbers:
        total += number
        if number < min_value:
            min_value = number
        if number > max_value:
            max_value = number

    return total, min_value, max_value

# 示例使用
numbers = [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5]
total, minimum, maximum = calculate_stats(numbers)
print(f"Sum: {total}, Min: {minimum}, Max: {maximum}")
