Lets say you have an multidimensional array
a = np.array([[1, 2], [3, 5], [4,5], [9,5]])
I want all the possible combinations of two arrays given the multidimensional array "a" so that:
[[1, 2],[3, 5]] , [[1, 2],[4,5]] ...
I have no idea how to due this. Does someone have some suggestions and tips?
You can use itertools.combinations function defined in this answer. This code creates the list of all the combinations.
import numpy as np
import itertools
a = np.array([[1, 2], [3, 5], [4,5], [9,5]])
combination=[]
for L in range(len(a) + 1):
for subset in itertools.combinations(a, L):
combination.append([list(sub) for sub in subset])
combination
