datatype of the answer given while using itertools

Question

Could anyone tell me what would be the data type of the answer given, while using itertools.combination(iterable, r)??

from itertools import combinations
def rSubset(arr, r):
 
    return list(combinations(arr, r))
if __name__ == "__main__":
    arr = [1, 2, 3, 4]
    r = 2
    print (rSubset(arr, r))

Answer 1

itertools.combinations returns a reference to an itertools.combinations class which is iterable. To clarify this using your data:

from itertools import combinations

arr = [1, 2, 3, 4]

for comb in combinations(arr, 2):
  print(comb)

Output:

(1, 2)
(1, 3)
(1, 4)
(2, 3)
(2, 4)
(3, 4)
