Shifting all elements in a 4x4 array to the right using NumPy

NumPy: Advanced Exercise-31 with Solution

Write a NumPy program to create a 4x4 array with random values and shift all elements one position to the right.

Sample Solution:

Python Code:

import numpy as np

# Create a 4x4 array with random values
array = np.random.random((4, 4))

# Print the original array
print("Original Array:\n", array)

# Shift all elements one position to the right
shifted_array = np.roll(array, shift=1, axis=1)

# Print the shifted array
print("Array after shifting all elements one position to the right:\n", shifted_array)

Output:

Original Array:
 [[0.56244965 0.13649834 0.11747523 0.32500712]
 [0.70083542 0.82382861 0.30299759 0.91059768]
 [0.94215098 0.40837075 0.02121122 0.90121581]
 [0.34578054 0.22681019 0.67214344 0.58693076]]
Array after shifting all elements one position to the right:
 [[0.32500712 0.56244965 0.13649834 0.11747523]
 [0.91059768 0.70083542 0.82382861 0.30299759]
 [0.90121581 0.94215098 0.40837075 0.02121122]
 [0.58693076 0.34578054 0.22681019 0.67214344]]

Explanation:

  • Import NumPy: Import the NumPy library to work with arrays.
  • Create a Random 4x4 Array: Generate a 4x4 array filled with random values using np.random.random.
  • Print the Original Array: Print the original 4x4 array for reference.
  • Shift Elements Right: Use np.roll with shift=1 and axis=1 to shift all elements one position to the right.
  • Print the Shifted Array: Print the array after shifting all elements one position to the right.
