The Most Numbers - stuck on empty sequence check

def checkio(*args):
    min_element = min(args)
    max_element = max(args)
    diff = 0
    if len(args) != 0:
        diff = max_element - min_element
        return diff
    else:
        return 0

Stuck with this code on an empty sequence check and getting this type of error: ValueError: min() arg is an empty sequence checkio, 2 <module>, 23 However, I wrote the condition, which filters 0 element argument list. I need some help!
