Passing Python slice syntax around to functions

Question

In Python, is it possible to encapsulate exactly the common slice syntax and pass it around? I know that I can use slice or __slice__ to emulate sl

Answer 1

One way (for simple slices) would be to have the slice argument either be a dict or an int,

ie

get_important_values([1, 2, 3, 4], lambda x: (x%2) == 0, {0: -1})

or

get_important_values([1, 2, 3, 4], lambda x: (x%2) == 0, 1)

then the syntax would stay more or less the same.

This wouldn't work though, for when you want to do things like

some_list[0:6:10..]
