I think I'm missing something. Daniel wants a `list.get` method with similar semantics to `dict.get`. So instead of writing:```try:x = lst[i]except IndexError:x = default```one could write `x = lst.get(i, default)`. How would you rewrite that with PEP 505?
I've also wanted this a couple of times, although I can't remember the reason. It's not just about traversing incomplete nested data structures. I don't see much disadvantage since the analogy with `dict.get` would make it very easy to learn and understand, to the point that I've wondered why this doesn't exist already.On Sat, Jun 27, 2020 at 5:09 PM Guido van Rossum <guido@python.org> wrote:Please read PEP 505 before rehashing this old idea.--On Sat, Jun 27, 2020 at 06:35 Daniel. <danielhilst@gmail.com> wrote:When I need to traverse nested dicts, is a common pattern to dosomedict.get('foo', {}).get('bar', {})But there is no such equivalent for arrays, wouldn't be nice if we can followsomedict.get('foo', {}).get('bar', []).get(10) ... ?What I do in this case is surround with try/except IndexError and set some variable to None, or wrap the try/except block in a function. But this is noise in my opinion, I just want to follow the same reasoning that I have with dicts: I'm searching for some path deep nested, and want a default if not found.What do you think?Regards_______________________________________________--“If you're going to try, go all the way.
