Combinaison

[Goodsayan]

Hello,

I'm new in python. I try to generate combinations of objects and calculate sums to characterize them.
A little confused, so I quickly give an example:

I have 3 objects "A", "B", "C" that I want to combine with each other by 2 for example.
In order to achieve this result
[[['A','B'], ['A','C'], ['B','C']]

Now objects have their characteristics
A= {'ST':5, 'SD':7, 'SA':2}
B= {'ST':1, 'SD':3, 'SA':3}
C= {'ST':2, 'SD':2, 'SA':4}

I would like that in addition to obtaining ['A','B'], I have the sum of characteristics of 'A' and 'B'such that[ST=6,SD=10,SA=5] and this for each of the possible combinations.

The expected result would be:
The combination A, B is ST=6,SD=10,SA=5
The combination A, C is ST=7,SD=9,SA=6
The combination B, C is ST=3,SD=5,SA=7

def comb(m, lst):
    if m == 0: return [[]]
    return [[x] + suffix for i, x in enumerate(lst)
            for suffix in comb(m - 1, lst[i + 1:])]
 
seq=['A','B','C']
print(comb(2, seq))

For the moment I can only do the combination....
Thank you in advance

Check out the itertools library. itertools.combinations(seq, 2) will give you all the combinations of two items in seq.
