How to reverse the columns of a 2D array with NumPy? Write a program to reverse the columns of a 2D array Sample data: [[0,1,2],[3,4,5],[6,7,8]] Sample output:[[210][5 4 3][8 76]]

Here's a code snippet that uses NumPy to reverse the columns of a 2D array:

import numpy as np

# Define the 2D array
arr = np.array([[0,1,2],[3,4,5],[6,7,8]])

# Reverse the columns
arr_reversed = arr[:, ::-1]

# Print the original and reversed arrays
print("Original array:")
print(arr)
print("Reversed array:")
print(arr_reversed)

The `::` syntax is used to slice the array. The first `:` indicates that we want to select all rows, and the `::-1` indicates that we want to reverse the order of the columns.

And here is the output for the given sample data:

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

As you can see, the columns have been reversed in the output array.
