Element-wise product of two 2-D lists

Question

I can\'t use Numpy or any other library function as this is a question I have to do, I have to define my own way.

I am writing a function that takes two lists (2 dimensi

Answer 1

You could use numpy arrays. They are your best option as they run on a C background and hence are much faster computationally

First, install numpy. Shoot up your terminal (CMD if you're in windows), type

pip install numpy

or, if in Linux, sudo pip install numpy

Then, go on to write your code

import numpy as np

list1=np.array([[2,3,5,6,7],[5,2,9,3,7]]) #2 dimensional list example
list2=np.array([[5,2,9,3,7],[1,3,5,2,2]])

prod = np.multiply(list1,list2)
# or simply, as suggested by Mad Physicist,
prod = list1*list2
