Does OCaml have String.split function like Python?

Question

I am using this to split strings:

 let split = Str.split (Str.regexp_string \" \") in
   let tokens = split instr in
 ....

But the problem

Answer 1

This is how I split my lines into words:

open Core.Std
let tokenize line = String.split line ~on: ' ' |> List.dedup

Mind the single quotes around the space character.

Here's the documentation for String.split: link
