How would I unpack a flat list? [duplicate]

Answer 1

Here's a hacky solution with iter and zip:

i =  [1, 2, 3, 4, 5, 6]
d = iter(i)

for a, b, c in zip(*[d]*3):
    print(a, b, c)

Output:

1 2 3
4 5 6

Additionally if you want it to iterate over everything when your original list isn't divisible by three you can use zip_longest from itertools:

from itertools import zip_longest


i =  [1, 2, 3, 4, 5, 6, 7]
d = iter(i)

for a, b, c in zip_longest(*[d]*3):
  print(a, b, c)

Output:

1 2 3
4 5 6
7 None None
