What is the pythonic way to calculate dot product?

Question

I have two lists, one is named as A, another is named as B. Each element in A is a triple, and each element in B is just a number. I would like to calculate the result defined as :

result = A[0][0] * B[0] + A[1][0] * B[1] + ... + A[n-1][0] * B[n-1]

I know the logic is easy but how to write in a pythonic way?

Thanks!

You can use the below-mentioned code to calculate the dot product in python:-

import numpy 

result = numpy.dot( numpy.array(A)[:,0], B)
