Second solution in Clear category for Completely Empty by Bronepoezd
from collections import Iterable
def completely_empty(val):
if isinstance(val, Iterable):
if isinstance(val, str):
# only '' is accepted
return not(val)
# A wellfounded iterable is completely empty when all its elements
# are completely empty.
return all(completely_empty(x) for x in val)
# a non-iterable is never completely empty
return False
