If your question is purely on the syntax, I suggest that you work through the examples given in the second link that @xzczd provided. If you are trying to construct a matrix and you don't know how, but you feel Transpose is the way, it would be better to tell us the matrix you want to construct.

As mentioned in Details and Options section of document of Transpose: For a square matrix m, Transpose[m,{1,1}] returns the main diagonal of m, as given by Diagonal[m]. »

| Jan 12, 2023 at 11:27 | comment | added | karry | Thanks @bmf I have a try, indeed they are different, and using MatrixForm@Transpose[{{1, 2}, {3, 4}}, {1, 1}], I get {1,4}, but I still can't understand. | |

And, in early version Transpose[{1,2,3}] isn't even legal: mathematica.stackexchange.com/q/244659/1871

To understand this last question you should compare MatrixForm@Transpose[{{1, 2}, {3, 4}}] to MatrixForm@Transpose[{{1, 2}, {3, 4}}, {1}] as a minimal example

| Jan 12, 2023 at 11:21 | comment | added | karry | @xzczd I understand the error, but what's the meaning of Transpose[{1,2,3}, {1}] , that is , why I need the n_k level? | |

……Then why are you using this syntax of Transpose? Strongly related: mathematica.stackexchange.com/a/14810/1871

| Jan 12, 2023 at 11:05 | comment | added | bmf | Also, perhaps you could tell what kind of list you are trying to construct | |
| Jan 12, 2023 at 11:02 | comment | added | bmf | You should read tperm which explains it explicitly with an example | |
