Adding in the loop construct and name bindings doesn't enhance my

multiplication of each element in a vector sequence.
What you need is to define a function dot-product, and not hijack the
name for a local value. Then the function's implementation is irrelevant
to you: it could use a list comp, or could use map, it could use a for-
loop, a while loop, recursion, or black magic:
scalar = dot_product(vec1, vec2)
Or use the appropriate libraries:
from numpy import dot
scalar = dot(vec1, vec2)
