How it comparing with
return vec1[0]*vec2[0]+vec1[1]*vec2[1]+vec1[2]*vec2[2]
and
x1, y1, z1 = vec1
x2, y2, z2 = vec2
return x1*x2+y1*y2+z1*z2
and
x1, y1, z1 = vec1
x2, y2, z2 = vec2
return sum(a*b for a, b in zip(vec1, vec2))
?
A 5% speed up may be not enough high for cluttering the educational example.
