Numpy's transpose(~) method flips the rows and columns, just as in the context of matrices.

Parameters

1. a | array-like

The input array.

2. axes | list of int | optional

The axis along which to perform the transpose. By default, flips the columns and rows for 2D arrays.

Return value

If a is a scalar, then a scalar is returned. Otherwise, a Numpy array is returned.

Examples

Consider the following 2D array:


        
        
            
                
                
                    a = np.array([[4,5],[6,7]])
a
                
            
            array([[4, 5],
       [6, 7]])

Taking the transpose gives:


        
        
            
                
                
                    np.transpose(a)
                
            
            array([[4, 6],
       [5, 7]])

Notice how the rows and columns flipped.
