Let’s see how to multiply array by scalar in Numpy Python library.
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.
Python simply multiplies each item by the number without any additional operations.
