One item String List into a String in a Haskell program

Question

I am using take 1 on a string list, so it takes the first string element from the list and puts it in a new list...

I.E: take 1 ["hello", "this", "is", "an", "example"]

Would output:

["hello"]

How can I make it so it outputs just:

"hello"

Is it easy?

(I only ever want the first element from a string list and I want it to output it as a string).

That would be the head function. But be careful: If you call it on an empty list, you'll get an error.

Yeah I was just about to answer myself saying i've solved it ('unwords' on the take 1 seems to work) Thanks anyway!

Another option, since String = [Char]: concat.
