Numpy.fliplr() Method: How to use Numpy.fliplr() Function in Python

Numpy fliplr() function is used to flip the array in the left-right direction. The shape of the array is preserved. The fliplr() function is used to flip array in the left/right direction. Python NumPy.fliplr() function flips the entries in each row in the left/right direction. The columns are preserved but appear in a different order than before.

Numpy fliplr()

The NumPy.fliplr(array) function flips the array(entries in each column) in left-right direction. The shape of an array is preserved.

Syntax

numpy.fliplr(array)

Parameters

The fliplr() function takes an array as a parameter.

Return Value

The fliplr() function returns the array the same array as flipped in the left-right direction.

Numpy.fliplr() Method with Example

Example 1: How to Use the numpy.fliplr() Method

import numpy as np

arr = np.arange(4).reshape((2, 2))
print("Original array : \n", arr)
print("\nFlipped array left-right : \n", np.fliplr(arr))

Output

Original array :
 [[0 1]
 [2 3]]

Flipped array left-right :
 [[1 0]
 [3 2]]

Example 2: Reshaping array left-right

import numpy as np

arr = np.arange(9).reshape((3, 3))
print("Original array : \n", arr)
print("\nFlipped array left-right : \n", np.fliplr(arr))

Output

Original array :
 [[0 1 2]
 [3 4 5]
 [6 7 8]]

Flipped array left-right :
 [[2 1 0]
 [5 4 3]
 [8 7 6]]
