Is there a way that you can preform a dot product of two lists that contain values without using NumPy or the Operation module in Python? So that the code is as simple as it could get?
For example:
V_1=[1,2,3]
V_2=[4,5,6]
Dot(V_1,V_2)
Answer: 32
Without numpy, you can write yourself a function for the dot product which uses zip
and sum
.
>>> def dot(v1, v2):
... return sum(x*y for x,y in zip(v1,v2))
...
>>> dot([1,2,3], [4,5,6])
32
