combination python
# 1. Print all combinations
from itertools import combinations
comb = combinations([1, 1, 3], 2)
print(list(combinations([1, 2, 3], 2)))
# Output: [(1, 2), (1, 3), (2, 3)]
# 2. Counting combinations
from math import comb

#Output: 120

python get all combinations of list
itertools.combinations(iterable, r)
how to get all possible combinations in python
all_combinations = [list(zip(each_permutation, list2)) for each_permutation in itertools.permutations(list1, len(list2))]
python possible combinations
import math
n=7
k=5
print(math.comb(n, k))
all possible combinations in python
import itertools
list1 = list(range(5, 10))
list2 = [1, 2, 3]
list = [list1, list2]
combination = [p for p in itertools.product(*list)]

python compute all combinations

Combination in python
