Question

Assuming I have object_list list which contains objects.

I want to check if my current iteration is is at the first or the last.

for object in object_list:
    do_something
    if first_indexed_element:
        do_something_else
    if last_indexed_element:
        do_another_thing

How can this be achieved? I know that I can use range and count index but if feels clumsy.

Regards

Answer 1

li = iter(object_list)

obj = next(li)

do_first_thing_with(obj)

while True:
    try:
        do_something_with(obj)
        obj = next(li)
    except StopIteration:
        do_final_thing_with(obj)
        break
