This question already has an answer here:

I often get Lists that contain a single item, like {name} or {{2,3,4}}.

Is there a function that simply takes the item out of the List without needing to use Part, like #[[1]]&?

  • $\begingroup$ Uh, isn't #[[1]]& a crude version of Part? The double bracket [[]] is a short version of Part, check a[[1]] // FullForm. $\endgroup$ – Gregory Rut May 11 '14 at 17:08

  • $\begingroup$ What's wrong with Part? It's a basic and very fast function. $\endgroup$ – m_goldberg May 11 '14 at 17:24

You can use First as in First@{{2,3,4}}. Not entirely sure though, why this should be preferable to [[1]].
