Alternatives of lists vs Alternatives of strings

$begingroup$


Obviously I am missing something obvious.



I have:



lis = {"a"}|{"b"}|{"c"}


but I want:



lis2 = "a"|"b"|"c"


Thanks as always for suggestions...

          Use lis[[All, 1]] or First /@ list. See Part and First.

            You can also Apply (@@@) Sequence at level 1:



            Sequence @@@ lis



            "a" | "b" | "c"




            Also



            ## & @@@ lis



            "a" | "b" | "c"




            Alternatively, use ReplaceAll to replace List with Sequence:



            lis /. List -> Sequence



            "a" | "b" | "c"




            Additional methods:



            MapAt[Sequence &, lis, {All, 0}]
            ReplacePart[lis, {_, 0} :> Sequence]
            lis[[All, 0]] = Sequence; lis


            all give "a" | "b" | "c".
