transpose numpy array 1d code example

Example 1: transpose matrix in python without numpy

def transpose(matrix):
    rows = len(matrix)
    columns = len(matrix[0])

    matrix_T = []
    for j in range(columns):
        row = []
        for i in range(rows):
           row.append(matrix[i][j])
        matrix_T.append(row)

    return matrix_T

Example 2: Python transpose np array

>>> a = np.array([[1, 2], [3, 4]])
>>> a
array([[1, 2],
       [3, 4]])
>>> a.transpose() #or a.T
array([[1, 3],
       [2, 4]])
