The only problem with that is if your iterable returns None as the
last item:
items = ["Something here", None]
item = None
for item in items:
print(repr(item))
if item is None:
print("Empty iterable") # wait, no it's not!
You'd have to use a sentinel like Ruud mentions further up-list:
x = sentinal = object()
for x in sequence:
print(repr(x))
if x is sentinal:
print("Empty iterable")
