numpy.ndarray.transpose — NumPy v2.4 Manual#numpy.ndarray.transpose

ndarray.transpose(﹡axes)

Returns a view of the array with axes transposed.

Refer to numpy.transpose for full documentation.

Parameters:

axes: None, tuple of ints, or n ints

• None or no argument: reverses the order of the axes.
• tuple of ints: i in the j -th place in the tuple means that the array’s i -th axis becomes the transposed array’s j -th axis.
• n ints: same as an n-tuple of the same ints (this form is intended simply as a “convenience” alternative to the tuple form).

Returns:

p: ndarray

View of the array with its axes suitably permuted.

See also:

transpose

Equivalent function.

ndarray.T

Array property returning the array transposed.

ndarray.reshape

Return a reshaped ndarray without changing data.

Examples:

>>> import numpy as np
>>> a = np.array([[1, 2], [3, 4]])
>>> a
array([[1, 2],
      [3, 4]])
>>> a.transpose()
array([[1, 3],
      [2, 4]])
>>> a.transpose((1, 0))
array([[1, 3],
      [2, 4]])
>>> a.transpose(1, 0)
array([[1, 3],
      [2, 4]])

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