Metrics Distance

Example
x = [3, 2, 7, 1]
y = [4, 3, 5, 2]

Manhattan Distances

$$dist(x,y) = \sum{|x_i-y_i|}$$

from scipy.spatial.distance import cityblock
cityblock(x, y)

Euclidean Distances

$$dist(x,y) = \sqrt{\sum{(x_i-y_i)^2}}$$

from scipy.spatial.distance import euclidean
euclidean(x, y)

Minkowski Distances

$$dist(x,y) = \sqrt[p]{\sum{(x_i-y_i)^p}}$$

from scipy.spatial.distance import minkowski
minkowski(x, y, 5)
