How to use Iterable?

Not sure I understand this one, the border is an index, not the value, how come that works? an what is the use of iterable here or it is it just for the type hints?

Iterable is a typehint for initial code

<pre class='brush: python'>def remove_all_before(items: list, border: int) -> Iterable: start_index = items.index(border) if border in items: return items[start_index:] else: return items </pre> that way is easier to understand?

you have a little mistake in there. <pre class='brush: python'>def remove_all_before(items: list, border: int) -> Iterable: if border in items: start_index = items.index(border) return items[start_index:] else: return items </pre> this is correct and works fine ;-)

<a href="https://en.wikipedia.org/wiki/Mistake">mistake</a>?

yep, your start_index = items.index(border) have to be in the if part. If it is bevore you dont ever get to the if...

Easy and short. This is the best way. :)
