Python – Bray-Curtis distance between two 1-D arrays

scipy.stats.braycurtis(array, axis=0) function calculates the Bray-Curtis distance between two 1-D arrays.

Parameters :
array: Input array or object having the elements to calculate the distance between each pair of the two collections of inputs.
axis: Axis along which to be computed. By default axis = 0

Returns : distance between each pair of the two collections of inputs.

Code #1 : 1D Array

from scipy.spatial.distance import braycurtis

a = [3, 1]

b = [2, 1]
arr1 = braycurtis(a, b)

print("Value of braycurtis is :", arr1)

Output:

Value of braycurtis is : 0.14285714285714285

Code #2 : 2D Array

from scipy.spatial.distance import braycurtis

arr1 = [1, 3, 27]

arr2 = [3, 6, 8]

print("Value of braycurtis is :", braycurtis(arr1, arr2))

Output:

Value of braycurtis is : 0.5
