Python code to multiply a NumPy array with a scalar value# Import numpy import numpy as np # Creating two numpy arrays arr1 = np.array([10, 20, 30]) arr2 = np.array([30, 20, 20]) # Display original arrays print("Original Array 1:\n",arr1,"\n") print("Original Array 2:\...
We can use two methods from thenumpymodule to achieve this. The first is by using thenumpy.multiply()function. This function works with lists and arrays, and multiplies every element from one list with the corresponding element at the other list. The final result will be stored in an array...
multiply() Return Value Themultiply()function returns an array that contains the result of element-wise multiplication between the input arrays. Example 1: Multiply Two Arrays importnumpyasnp array1 = np.array([10,20,30]) array2 = np.array([2,4,6]) # perform element-wise multiplication b...
To understand this example, you should have the knowledge of the following Python programming topics: Python for Loop Python List Python Matrices and NumPy ArraysIn Python, we can implement a matrix as nested list (list inside a list). We can treat each element as a row of the matrix. ...
