In this article, I will present the Erlang’s lists module and its most important functions. Combine list comprehensions and other Erlang datastructures L = [{apple, 5}, {banana, 7}, {lemon, 1}, {apple, 2}]. 26> [F|| F <- L, apple==element(1,F)]. [{apple,5},{apple,2}] 27> [F|| F <- L, lemon=/=element(1,F)]. [{apple,5},{banana,7},{apple,2}] 28> [{Name, Q*2}|| {Name, Q} <- L]. [{apple,10},{banana,14},{lemon,2},{apple,4}] When two elements compare equal, the element from the sub-list with the lowest position in ListOfLists is picked before the other element.

Erlang är ett generellt programspråk som från början utvecklades på forskningsavdelningen hos telebolaget Ericsson AB vid utvärderingen av olika programspråk för implementation av styrsystemen i telefonväxlar. Språket är ett funktionellt programspråk, utan typdeklarationer och med dynamisk typning. Eftersom språket är designat för parallell bearbetning på flera sammankopplade system är det också synnerligen väl lämpat för användning på moderna flerkärniga you will create a new list which is copy of the elements in List1, followed by List2.Looking at how lists:append/1 or ++ would be implemented in plain Erlang, it can be seen clearly that the first list is copied: Se hela listan på tutorialspoint.com Erlang List & List Module.
