Itertools combination Memory error with Python

Question

I have a Memory error when I use combinations with a big list of list like len 735. Any way to do a similar process but without the error?

from itertools import combinations

valores = [[5, 10.732544898986816], [9, 10.596251487731934], [11, 10.70582103729248]]
f = list(combinations(valores, 3))

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
MemoryError

Answer 1

If your list has 735 elements, then there are (735 choose 3) = 65907695 combinations of three elements. There is probably no need to keep all of these 3-tuples in memory at the same time, so don't build a list out of them; just iterate directly.

for c in combinations(valores, 3):
    # do something with c
