Creating an n-dimensional array of length n
📁 список, python, вопрос, пример
Is it possible to create an n-dimensional array? If so, how can it be implemented? If a matrix is a "list of lists", then it would look something like this:
[ [ [...[]...] ],[ [...[]...] ] ]Well, or to make it clearer, like n nested brackets, picture below,
(a1[...[]...]b1, a2_m[...[]...]b2_m,...)And how to implement this in code? If, say, I need to input n from the keyboard. Many thanks!

This is not split - it's input throwing an exception. And why is that? Ingratitude. It says the following - input does two things:
1) Reads from stdin.
2) Everything that is read gets executed (eval).
Accordingly, the string 1 2 3 cannot be executed due to invalid syntax. In Py3, the behavior of input() was changed so that people wouldn't get confused anymore. Use . Or Python3. You can also use the library so that when you suddenly migrate to another version, your code won't break, because in Py3 the raw_input() function is missing.
