How to multiply array by scalar in Python

To multiply an array by a scalar, simply use the asterisk (*) operator. No specific NumPy function is required for this operation.

import numpy as np

my_array = np.array([1, 2, 3, 4, 5])
print(my_array)

my_scalar = 5
multiplied_array = my_array * my_scalar

print(multiplied_array)

The given array has been multiplied by the specified scalar, meaning that each element of the array has been multiplied by that scalar.
