How can I trasform a (1,16) array in a (1,16,1) array with np.newaxis?

This might help you You have to put the np.newaxis on the location of the dimenstion where you want this new axis.
code :
board[np.newaxis,:] -> puts the axis in the first dimension [1,1,16]
board[:,np.newaxis] -> puts the axis in the second dimension [1,1,16]
board[:,:,np.newaxis] -> puts the axis in the third dimension [1,16,1]

How to "trasform" an array of hash so that you can customize logic to access its data?

I hope this helps you . If I understand your requirements correctly, I think you are better off constructing a hash from account id to account data. Perhaps something like this will work:
code :
arr = [
  {
    "account" => {
       "id"   => 45, 
       "name" => "Test_name", 
       "..."  => "..."
     }
   }, 
   {
     "other"  => {
       "sub_other" => "..."
     }
   }
]

account_hashes = arr.select {|item| item.keys.first == "account"}

answer = account_hashes.inject({}) do |acc, item| 
    acc[item["account"].delete("id")] = item["account"]
    acc
end

will be helpful for those in need Problem: I have a cell array and every cell of this array has an other cell that contains a string: I want to trasform the cell array in a matrix of strings. How can i do? I have tried to use cell2mat but matlab gives an error: 'Cannot support cell arrays containing cell arrays or objects.' , Suppose you have a row cell array of N cell arrays of P strings:
code :
C = {{'abc', 'de', 'f'}, {'g', 'hi', 'jkl'}};
R1 = vertcat(C{:});
R2 = horzcat(C{:});

Store multidimensional numpy array slice with newaxis to object

To fix this issue You can construct the index tuple manually, but NumPy includes a helper for it:
code :
slice_tuple = np.s_[np.newaxis, ..., :, np.newaxis]
class IndexHelper(object):
    def __getitem__(self, arg):
        return arg

s_ = IndexHelper()

To fix the issue you can do I need to perform a Jolt transformation on the below example json: , Can do it in a single shift.
code :

      "0": {
        "DOCUMENT_HEADER_ID": "DOCUMENT_HEADER_ID"

To fix this issue , You can just reshape and transpose the values:
code :
np.transpose(df.values.reshape(2,9))
df.values.reshape(2,-1).T
array([[  1,   4],
       [  6,   9],
       [  0,   1],
       [  2,   5],
       [  7,  10],
       [  1,   0],
       [  3,   5],
       [  8,   4],
       [  0, 100]], dtype=int64)
