How to multiply array by scalar in Python

To multiply array by scalar you just need to use usual asterisk. You don’t need any dedicated Numpy function for that purpose.

import numpy as np

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

scalar = 5
multiplied_array = array * scalar

print(multiplied_array)

Given array has been multiplied by given scalar. Meaning that every element of array has been multiply by that scalar.
Python just multiply items by the number and does nothing else.
