python - multiply and add each element in list a with list b

Question

function:

def unique_common(a, b):

I have two lists, lets say:

a = [2, 3, 5, 7, 9] 

and another list

b = [5, 8         


        

Answer 1

Perhaps the solution would be to use NumPy, where the code should be very self-explanatory :

import numpy as np

a = np.array([2,3,5,7,9])
b = np.array([5,8,4,1,11])

c = a*b
d = np.sum(c)
print(d)
