checking for last item in for loop

[Yoriz]

Here one way of doing it which returns a tuple of bool, item, the bool is True if its the last item.

items = range(3)

def iter_is_last(items):
    iterable = iter(items)
    previous = next(iterable)
    for last in iterable:
        yield False, previous
        previous = last
    yield True, last

for is_last, item in iter_is_last(items):
    if is_last:
        print(f'Last item is {item}')
    else:
        print(f'Item is {item}')

Output:
Item is 0
Item is 1
Last item is 2
