Lists get sublist

Tato sekce je dostupná pouze v angličtině.

This block returns a sublist (slice) of a list variable.

First argument is a variable containing list, second and third argument should be either Int or None. The default argument is None and means a skipped slicing option (i.e. setting pulldown to “first” or “last”).

In case slicing can’t be performed, because the slicing index is for example a string, None is returned.
