将列表转换为可除的浮点数

def convert_to_divisible_float(lst):
    # 检查列表是否为空
    if len(lst) == 0:
        return None  # 或者返回特定的结果

    result = []
    for num in lst:
        # 确保元素为数字类型
        if not isinstance(num, (int, float)):
            return None  # 或者进行错误处理

        # 转换为浮点数类型
        num = float(num)
        result.append(num)

    return result

# 示例用法
my_list = [1, 2, 3, 4, 5]
converted_list = convert_to_divisible_float(my_list)
if converted_list is not None:
    # 进行除法运算
    divided_list = [num / 2 for num in converted_list]
    print(divided_list)
