I am working on a project and it involves a lot of manipulating lists. I'm trying to group objects in the list together, e.g the list:
["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P"]
would become:
["ABCD","EFGH","IJKL","MNOP"]
But I cannnot seem to find a way to do this. Please help?
