如何在列表中追加最接近的值

def append_closest_value(target_list, target_value):
    closest_value = None
    min_difference = float('inf')  # 初始化差值为正无穷大

    for value in target_list:
        difference = abs(value - target_value)  # 计算差值的绝对值
        if difference < min_difference:
            min_difference = difference
            closest_value = value

    target_list.append(closest_value)  # 将最接近的值追加到列表中

# 示例用法
my_list = [1, 3, 5, 7, 9]
my_value = 6
append_closest_value(my_list, my_value)
print(my_list)  # 输出：[1, 3, 5, 7, 9, 5]
