Question

Is there a way to drop the first element of a 3 element tuple, so I get a 2 element tuple without having to make another function for this purpose?

(a,b,c)->(b,c)

Basically I have to use a function, which creates a 3 element tuple and then I have to use a function that only uses the last two element of it.

Thank you for your answers.

Answer 1

Your question almost has the required function itself!

\(a,b,c)->(b,c)

is the function you need. It is an “anonymous” function defined on the fly, you need not give it a name. So for example if you have

someFunc :: someType -> (Int, Char, Bool)

You could do

(\(a,b,c)->(b,c)) (someFunc someValue)

to get the second and third component of someFunc someValue.
