Dot Product In Python Without Numpy

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

Solution 1:

Without numpy, you can write yourself a function for the dot product which uses zip and sum.

>>>defdot(v1, v2):...returnsum(x*y for x, y inzip(v1, v2))...>>>dot([1, 2, 3], [4, 5, 6])
32

As of Python 3.10, you can use zip(v1, v2, strict=True) to ensure that v1 and v2 have the same length.

Solution 2:

defdot_product(x, y):
    dp = 0for i inrange(len(x)):
        dp += (x[i]*y[i])
    return dp

sample1 = [1,2,3,4,5]
sample2 = [2,1,1,1,1]

dot_product(sample1, sample2) #16
