How can I quickly create a List[开发者_如何学GoInt] that has 1 to 100 in it?
I tried List(0 to 100), but it returns List[Range.Inclusive]
Thanks
Try
(0 to 100).toList
The code you tried is creating a list with a single element - the range. You might also be able to do
List(0 to 100:_*)
Edit
The List(...) call takes a variable number of parameters (xs: A*). Unlike varargs in Java, even if you pass a Seq as a parameter (a Range is a Seq), it will still treat it as the first element in the varargs parameter. The :_* says "treat this parameter as the entire varargs Seq, not just the first element".
If you read : A* as "an (:) 'A' (A) repeated (*)", you can think of :_* as "as (:) 'something' (_) repeated (*)"
List.range(1,101)
The second argument is exclusive so this produces a list from 1 to 100.
