Python 按上界生成列表

我想生成以下类型的列表

输入

2,5

输出

[1,1],[1,2]

[2,1],[2,2]

[3,1],[3,2]

[4,1],[4,2]

[5,1],[5,2]

[1,1,1] [1,1,2] [1,1,3] [1,1,4]

[1,2,1] [1,2,2] [1,2,3] [1,2,4]

[1,3,1] [1,3,2] [1,3,3] [1,3,4]

[2,1,1] [2,1,2] [2,1,3] [2,1,4]

[2,2,1] [2,2,2] [2,2,3] [2,2,4]

[2,3,1] [2,3,2] [2,3,3] [2,3,4]

[1,1,1] [1,1,2] [1,1,3]

[1,2,1] [1,2,2] [1,2,3]

i、 e.让每个索引从1运行到它的上限，我可以使用循环，如下所示

for i in range(1,3)

for j in range (1,6)

....

但是当输入变成

[1,2,3,4,5]…

例如

输入

输出

[1,1],[1,2]

[2,1],[2,2]

[3,1],[3,2]

[4,1],[4,2]

[5,1],[5,2]

[1,1,1] [1,1,2] [1,1,3] [1,1,4]

[1,2,1] [1,2,2] [1,2,3] [1,2,4]

[1,3,1] [1,3,2] [1,3,3] [1,3,4]

[2,1,1] [2,1,2] [2,1,3] [2,1,4]

[2,2,1] [2,2,2] [2,2,3] [2,2,4]

[2,3,1] [2,3,2] [2,3,3] [2,3,4]

[1,1,1] [1,1,2] [1,1,3]

[1,2,1] [1,2,2] [1,2,3]

输入

输出

[1,1],[1,2]

[2,1],[2,2]

[3,1],[3,2]

[4,1],[4,2]

[5,1],[5,2]

[1,1,1] [1,1,2] [1,1,3] [1,1,4]

[1,2,1] [1,2,2] [1,2,3] [1,2,4]

[1,3,1] [1,3,2] [1,3,3] [1,3,4]

[2,1,1] [2,1,2] [2,1,3] [2,1,4]

[2,2,1] [2,2,2] [2,2,3] [2,2,4]

[2,3,1] [2,3,2] [2,3,3] [2,3,4]

[1,1,1] [1,1,2] [1,1,3]

[1,2,1] [1,2,2] [1,2,3]

有什么优雅的方法吗？（最好使用python）

将它们全部转换为

范围并使用。Star解包使操作变得简单：

allranges = (range(1, lim+1) for lim in inputs)
for prod in itertools.product(*allranges):
    print(prod)
