[Solved] How to rotate arrays in python?
Array: [ [ 0 1 2 ] [ 3 4 5 ] ] I want this array to be: [ [ 0 3 ] [ 1 4 ] [ 2 5 ] ] It is possible using for loop but that won't be a true numpy coding.

Can one transpose

Arrray2= zip(*Array)
but I would propose numpy indeed.

Find the word ANNA in this matrix
AXXX
XNXX
XXNX
XXXA
If you try with a code, you would search rows
Maybe transpose matrix and again search rows.
Now it is up to diagonals.
I would like to transpose the matrix so that again horizontal search is possible.

This is the most quick builtin python way to do it
>>>list(zip([
[1,2,3],
[4,5,6],
[7,8,9]])
[[1,4,7],[2,5 8],[3,6,9]]

Everything works. But np.transpose is best and faster i think. Thanks Jay Matthews

Valmob101 array i think yes but surely not a matrix.
I try to find an elegant way for this transition due to a challange that finds words in a matrix.
If this transformation is possible with acceptable effort, the search for words can be kept horizontal and not duagonally.

Oma Falk you can also do vertical slice on 2d numpy arrays like
arr[0] is first row
arr[:,0] is first column
Separate the dimensions with comma, and each dimension can have a fixed index or a slice as you would slice any list.

Oma Falk is it an array?
