Topic: Generate Set from List
Christian K (Mar 12 2024 at 13:31):
Is there a way to generate a List from a (possibly infinte) Set so that it includes every element of the Set?
def list_from_set {α : Type} (x : Set α) : List α := by sorry
def lst := list_from_set {1,2,3,4} -- -> [1,2,3,4]
def lst2 := list_from_set {x : ℕ | x > 2} -- -> [list with all Natural numbers > 2]

there is a Function Finset.toList for Finsets docs
i dont know if i remember correctly, but i think Lists have to be finite
Ruben Van de Velde (Mar 12 2024 at 13:52):
Yes, a List is finite

Ok, makes sense. I figured out another way to get around using a list, thank you for the clarification.
