I've got this line: for k in range(len(tcombo)): tcombo_ep.append(list(combinations(tcombo, k+1)))
generating every possible length combination of tcombo. I then test them, and throw most of them away. I need to do this differently, it gets way too big (crashes my computer). I'm going to play some more, but I think I need to test the combinations as they're generated... and then only add them to a list (probably better: a set) if they meet a requirement (something like sum(specific.combination(tcombo) == goal)) AND if they are not already part of that list (the uniqueness issue is why a set might be better) I'm partially asking in order to clarify the question in my mind, but any help will be appreciated. I don't really understand lambda functions yet, but I can sort of imagine they might work here somehow... or not.
