I have a list and need to get all permutations. But I can do permutations only inside list subsets.
So for example I have list like this [1,2,3,4]
I split it into two subsets [1,2], [3,4]
And I want to get an iterable which will give me
[1,2], [3,4]
[2,1], [3,4]
[1,2], [4,3]
[2,1], [4,3]
So it is equivalent to nested loops. But number of subsets can be different and I cant code it as loops
Try:
from itertools import permutations, product
x,y=[1,2],[3,4]
z=list(product(permutations(x), permutations(y)))
Outputs:
[((1, 2), (3, 4)), ((1, 2), (4, 3)), ((2, 1), (3, 4)), ((2, 1), (4, 3))]
you can try with this
import itertools
subset= [1,2,3,4]
for sin itertools.combinations(subset, 2):
print(s)
