Is it advantageous to use a generator instead of a set here?

Question

Python

I have a set of all_members, it stores positive integers. So far there are not many of them, but I want to optimize for more loads from the very beginning. So, is it profitable to convert it into a generator if it is then used only in a loop? They say that generators, if needed only for a cycle, are more productive, but in order for him to generate elements of a set, he needs to store this set somewhere? Tell

all_members = itertools.chain.from_iterable([all_members])

Answer 1

Generators are beneficial if (all) data does not need to be stored, i.e. they took it somewhere, transferred it somewhere, as a result, it turns out, as it were, a flow of information without consuming memory.
