Is there something similar to the slice notation in Python in Scala?

I think this is really a useful operation that should be incorporated in all languages.

    Equivalent method in Scala (with a slightly different syntax) exists for all kinds of sequences:

    scala> "Hello world" slice(0,4)
    res0: String = Hell
    
    scala> (1 to 10) slice(3,5)
    res1: scala.collection.immutable.Range = Range(4, 5)
    

    The biggest difference compared to slicing in Python is that start and end indices are mandatory in Scala.
