Why you make a copy of original sequence and also sort it? It make your code work longer than it can be.
BTW in python you can swap elements in list like this:
arr[i], arr[i + 1] = arr[i + 1], arr[i]
with no temp variable.

You don't need to convert set to list every time, instead you can simply iterate through set.

It's a 3 lines actually, you just don't type enter after ':'. If you truly need a one or two line, you can do this:
checkio = lambda *args: float(max(args)) - float(min(args)) if len(args) > 1 else 0
or
def checkio(*args):
return float(max(args)) - float(min(args)) if len(args) >
