How to add to 2D list the total equal to Y combinations of X numbers of list of N numbers in Python

Answer 1

from itertools import combinations 

N = 11
lst = list(range(1, N))

X = 5
comb = combinations(lst, X) 
  
two_d = [[] for i in range(20)] 

Y = 31
i = 0
for ol in list(comb):
    sum = 0
    tmp_lst = []
    for n in ol:
       sum += n
       tmp_lst.append(n)
    if (sum == Y):
       two_d[i] = tmp_lst
       i = i + 1
 
for i in range(len(two_d)):     
    print(two_d[i])
