在 Python 中，可以使用嵌套列表的方式创建多维列表。要创建一个五维空列表，可以使用嵌套循环的方式来实现。下面是一个示例代码：

# 创建五维空列表
dim1 = 3  # 第一维大小
dim2 = 4  # 第二维大小
dim3 = 2  # 第三维大小
dim4 = 5  # 第四维大小
dim5 = 6  # 第五维大小

# 使用嵌套循环创建五维空列表
five_dim_list = [[[[[None for _ in range(dim5)] for _ in range(dim4)] for _ in range(dim3)] for _ in range(dim2)] for _ in range(dim1)]

print(five_dim_list)

在上面的代码中，使用了五层嵌套循环来创建五维空列表。dim1代表第一维的大小，dim2代表第二维的大小，以此类推。通过循环遍历每一维的大小，使用 None 来初始化列表的元素。

输出结果为：

[[[[[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]]], [[[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]]], [[[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]], [[None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None], [None, None, None, None, None, None]]]]

可以看到，five_dim_list是一个五维空列表，每一维都有特定的大小。
